## Answers

Answer: {x,y} = {3,-2} Step-by-step explanation:// Solve equation [1] for the variable y [1] y = 2x - 8// Plug this in for variable y in equation [2] [2] 3x - 2•(2x-8) = 13 [2] -x = -3// Solve equation [2] for the variable x [2] x = 3 // By now we know this much : x = 3 y = 2x-8// Use the x value to solve for y y = 2(3)-8 = -2 Solution : {x,y} = {3,-2}
