A, x=-13 or x=21.
-13 - 4 (-13+ -4) is equal to -17. Due to absolute value bars, it is now positive 17.
21-4 = 17
Answer:
x = 8, y = 2
Step-by-step explanation:
Multiply the second equation by -2:
x + 6y = 20
-2x - 6y = -28
Add the equations and simplify:
-x = -8
x = 8
Plug x = 8 back into the first equation and solve for y:
8 + 6y = 20
6y = 12
y = 2
