Question

Use the substitution method to solve the system of equations. Choose the correct ordered pair.

x + 2y = 12

y = x + 3

Answer 1

(2,5)

Answer 2

2x + 3y = 13

x = 2

Answer 3

x+2(x+3) = 12
x+2x+6 = 12
3x = 12-6
x = 6/3
x = 2

y = 2+3
y = 5

Answer 4

2x + 3y = 13

x = 2
3y=13-4
3y=9
y=3
