Answer:
x = - 3, y = - 6
Explanation:
Given the 2 equations
- 14x = - 72 - 19y → (1)
9x = 87 + 19y → (2)
Add the 2 equations term by term to eliminate the y- term
- 5x = 15 ( divide both sides by - 5 )
x = - 3
Substitute x = - 3 into either of the 2 equations and evaluate for y
Substituting into (2)
9(- 3) = 87 + 19y
- 27 = 87 + 19y ( subtract 87 from both sides )
- 114 = 19y ( divide both sides by 19 )
- 6 = y
Thus x = - 3, y = - 6
