Question:

- Explain how you would start to solve the given system of equations below:
(You do not have to solve it)
4x – 9y = -21
4x + 3y = -9

Answers

Answer:Step-by-step explanation:

1. Solve by using the Elimination method for solving systems of equations.2. Top equation, minus, the other equation on the bottom. (4x-9y=-21)-(4x+3y=-9)3. Subtract like terms.4x-4x = 0-9y - 3y = -12y-21 - -9 = -304. Isolate for yy= -30/-12 =5/25. Plug the value of y into original equation and isolate for x.
