Answer:
y = 1, x = - 8
or
(-8, 1)
Step-by-step explanation:
-x + 4y = 12
x + y = -7
add the equations together
0x + 5y = 5
5y = 5
y = 1
substitute y for 1 in one of the original equations to find x
x + y = -7
x + 1 = -7
x + 1 - 1 = - 7 - 1
x = - 7 - 1
x = -8

the second one I can't give a explanation cause my wrist is broken so it's harder to type hope this helps
Answer: x = 4
Step-by-step explanation:
5x + 34 = -2(1 - 7x)
5x + 34 = -2 + 14x Multiply -2 to 1 and -7x
5x + 36 = 14x Add 2 to both sides
36 = 9x Subtract 5x to both sides
4 = x Divide 9 to both sides
