x = - 4 and y = 27/6
Step-by-step explanation:
- (8x + 6y = - 5) which converts to - 8x - 6y = 5
10x + 6y = - 13
simplify from there
-8x + 10x = 2x; - 6y + 6y = 0; 5 - 13 = - 8
soo, now you have
2x = - 8
x = - 4
then, plug in to find y
8 (-4) + 6y = - 5
-32 + 6y = - 5 add 32 on both sides
6y = 27 divide both sides by 6
y = 27/6 or 4.5
