1,5 I think because the x is negative so it would become positive and the y would stay the same.

Answer:
(- 1, 2 )
Step-by-step explanation:
Given the 2 equations
2x + 5y = 8 → (1)
- x + 3y = 7 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate the term in x, thus
- 2x + 6y = 14 → (3)
Add (1) and (3) term by term to eliminate the x- term
11y = 22 ( divide both sides by 11 )
y = 2
Substitute y = 2 in either of the 2 equations and evaluate for x
Substituting in (1)
2x + 5(2) = 8
2x + 10 = 8 ( subtract 10 from both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1
Solution is (- 1, 2 )
