Question

Use the substitution method to solve the following system of equations.

3x + 5y = 3
x + 2y = 0

A. (1, 1)

B. (6, –3)

C. (6, 1)

D. (1, –3)

Answer 1

First solve for x in the 2nd equation by subtracting 2y on both sides of the equation
x + 2y = 0
x = -2y

Answer 2

Now substitute what x equals in the 1st equation
3x + 5y = 3
3(-2y) + 5y = 3
-6y + 5y = 3
-y = 3
y = -3
