-2\times 2x+y-1=-12
Multiply both sides of the equation by 10, the least common multiple of 5,10.
-4x+y-1=-12
Multiply -2 and 2 to get -4.
-4x-1=-12-y
Subtract y from both sides.
-4x=-12-y+1
Add 1 to both sides.
-4x=-11-y
Add -12 and 1 to get -11.
-4x=-y-11
The equation is in standard form.
\frac{-4x}{-4}=\frac{-y-11}{-4}
Divide both sides by -4.
x=\frac{-y-11}{-4}
Dividing by -4 undoes the multiplication by -4.
x=\frac{y+11}{4}
Divide -11-y by -4.
-2\times 2x+y-1=-12
Multiply both sides of the equation by 10, the least common multiple of 5,10.
-4x+y-1=-12
Multiply -2 and 2 to get -4.
y-1=-12+4x
Add 4x to both sides.
y=-12+4x+1
Add 1 to both sides.
y=-11+4x
Add -12 and 1 to get -11.
