Answer:
what you do is you want to get the x by it self so you would subtract the x and put it on the other side. like this: 10y=-9-x. OK so you would subtract -9 and put it on the other side like this: 9 + 10y=-x. but you can't have a negative x so u would do -9 + 10y=x.

Answer:
x=-3
Step-by-step explanation:
39 - 7X = —4 ( 7X +7 ) + 4
Distribute
39 -7x = -28x -28 +4
Combine like terms
39 -7x =-28x -24
Add 28x to each side
39 -7x+28x =-28x+28x -24
39+21x=-24
Subtract 39 from each side
39-39+21x = -24 -39
21x = -63
Divide by 21
21x/21 = -63/21
x = -3
