Solve the system of equations 2x + 3y = 40 and –2x + 2y = 20. A. x = –10, y = 20 B. x = 10, y = 20 C. x = 2, y = 12 D. x = –6, y = 4
2x + 3y = 40 –2x + 2y = 20 (2x + 3y = 40) + (–2x + 2y = 20) 5y = 60 y = 60/5 y = 12 2x + 3(12) = 40 2x + 36 = 40 2x = 40 - 36 2x = 4 x = 4/2 x = 2 Solution set: x = 2, y = 12

2x + 3y = 40
–2x + 2y = 20

(2x + 3y = 40) + (–2x + 2y = 20)
5y = 60
y = 60/5
y = 12

2x + 3(12) = 40
2x + 36 = 40
2x = 40 - 36
2x = 4
x = 4/2
x = 2

Solution set: x = 2, y = 12
