find the solution to the system of equations.
−7x−2y=14

6x+6y=18

x=

y=

x = - 4, y = 7

Step-by-step explanation:

Given the 2 equations

-7x - 2y = 14 → (1)

6x + 6y = 18 → (2) ← Divide all terms by 6

x + y = 3 ← rearrange expressing x in terms of y, subtract y from both sides

x = 3 - y → (3)

Substitute x = 3 - y into (1)

- 7(3 - y) - 2y = 14

- 21 + 7y - 2y = 14

- 21 + 5y = 14 ( add 21 to both sides )

5y = 35 ( divide both sides by 5 )

y = 7

Substitute y = 7 into (3) for corresponding value of x

x = 3 - 7 = - 4

after simplifying it i got: -36.25 as my answer. hope that !
