Answer:
x = - 1 , y = 3
Step-by-step explanation:
given the system of equations
7x - 2y = - 13 → (1)
- 7x - 6y = - 11 → (2)
adding the 2 equations term by term will eliminate x
(7x - 7x) + (- 2y - 6y ) = - 13 - 11
0 + (- 8y) = - 24
- 8y = - 24 ( divide both sides by - 8 )
y = 3
substitute y = 3 into either of the 2 equations and solve for x
substituting into (1)
7x - 2(3) = - 13
7x - 6 = - 13 ( add 6 to both sides )
7x = - 7 ( divide both sides by 7 )
x = - 1
The solution is x = - 1 , y = 3
