-x+10=-2(x-1) i really need help

Answer 1

-x+10=-2(x-1)
expand the right side
-x + 10 = -2x + 1
add 2x to both sides
-x + 2x + 10 = 1
combine the x's and subtract 10 from both sides
x = 1-10
x = -9

Once you are more comfortable with those kind of steps, your
solution will look like this
-x+10=-2(x-1)
-x+10 = -2x + 1
x = -9
