How to solve systems of equations: 4x+5y=11                                                     2x+6y=16          show steps plz

4x+5y = 11 and 2x+6y = 16Let's start by solving 4x+5y = 11 for the variable x.Move the 5y to the right hand side by subtracting 5y from both sides, like this:From the left hand side:5y - 5y = 0The answer is 4xFrom the right hand side:The answer is 11-5yNow, the equation reads:4x = 11-5y To isolate the x, we have to divide both sides of the equation by theother variablesaround the x on the left side of the equation.The last step is to divide both sides of the equation by 4 like this:To divide x by 1The x just gets copied along in the numerator.The answer is x4x ÷ 4 = xTo divide 11-5y by 4divide each term in 11-5y by 4 term by term.11 ÷ 4 =11/4To divide y by 1The y just gets copied along in the numerator.-5y ÷ 4 =The solution to your equation is:x =Next, let's solve 2x+6y = 16 for the variable y.Move the 2x to the right hand side by subtracting 2x from both sides, like this:From the left hand side:2x - 2x = 0The answer is 6yFrom the right hand side:The answer is 16-2xNow, the equation reads:6y = 16-2x To isolate the y, we have to divide both sides of the equation by theother variablesaround the y on the left side of the equation.The last step is to divide both sides of the equation by 6 like this:To divide y by 1The y just gets copied along in the numerator.The answer is y6y ÷ 6 = yTo divide 16-2x by 6divide each term in 16-2x by 6 term by term.16 ÷ 6 =To divide x by 1The x just gets copied along in the numerator.-2x ÷ 6 =The solution to your equation is:y =Now, plug the earlier result, x=11/4-5/4y, in for x everywhere it occurs in y=8/3-1/3x.This gives y=8/3-1/3(11/4-5/4y). Now all we have to do is solve this for y,to have our first solution.8/3 evaluates to 1/3 evaluates to 11/4 evaluates to 5/4 evaluates to Multiply y andMultiply y and 1The y just gets copied along.The answer is yy5/4*y evaluates to 11/4-5/4*y evaluates to Multiply bywe multiply by each term in term by term.This is the distributive property of multiplication.Multiply and1 × =Multiply andMultiply 1 and yThe y just gets copied along.y × =1/3*(11/4-5/4*y) evaluates to  - =The answer is8/3-1/3*(11/4-5/4*y) evaluates to Move the to the left hand side by subtracting from both sides, like this:From the left hand side:y - =The answer isFrom the right hand side: - = 0The answer isNow, the equation reads: = To isolate the y, we have to divide both sides of the equation by theother variablesaround the y on the left side of the equation.The last step is to divide both sides of the equation by like this:To divide y by 1The y just gets copied along in the numerator.The answer is y ÷ = y ÷ = 3The solution to your equation is:y = 3Lastly, to find the solution for x, we plug this answer for y into the earlier result thatx=11/4-5/4y.This gives x=11/4-5/4(3). Now, simplify this.11/4 evaluates to 5/4 evaluates to Multiply and 315/4*(3) evaluates to 11/4-5/4*(3) evaluates to -1x= -1So, the solutions to your equations are:x= -1 and y= 3The answer is xThe answer is y
