Question

Solve each system using substitution

Answer 1

Answer: x = 3 and y = 1

Explanation:

y = (-2/3x + 3)

Plug value of y into top equation.

x - 2/3x + 3 = 4

1/3x = 1

x = 3

x = (-3/2y + 4.5)

Plug value of x into top equation.

y - 3/2y + 4.5 = 4

-0.5y = -0.5

y = 1

Proof:

3 + 1 = 4

2(3) + 3(1) = 9
