3x + 2y = -9<br> 4x - 2y = -26<br> please help I have to solve this with the elimination method
Paladinen [302]

Answer:

x = - 5, y = 3

Step-by-step explanation:

Given the 2 equations

3x + 2y = - 9 → (1)

4x - 2y = - 26 → (2)

Adding (1) and (2) term by term eliminates the y- term, that is

7x = - 35 ( divide both sides by 7 )

x = - 5

Substitute x = - 5 into either of the 2 equations and solve for y

Substituting into (1)

3(- 5) + 2y = - 9

- 15 + 2y = - 9 ( add 15 to both sides )

2y = 6 ( divide both sides by 2 )

y = 3
