Question

Select the correct answer.

Find the solution to the system of equations given below using elimination.
3x + 2y = -3
9x + 4y = 3

Answer 1

x = 3 and y= -6 or (3, -6)

Explanation:

-3(3x + 2y = -3) 3x + 2(-6) = -3

9x + 4y = 3 3x -12 = -3

3x = 9

-9x - 6y = 9 x = 3

9x +4y = 3

-2y = 12

y = -6
