x+11-4x=46-7x+2-A
Add 6 and 5 to get 11.
-3x+11=46-7x+2-A
Combine x and -4x to get -3x.
-3x+11=48-7x-A
Add 46 and 2 to get 48.
48-7x-A=-3x+11
Swap sides so that all variable terms are on the left hand side.
-7x-A=-3x+11-48
Subtract 48 from both sides.
-7x-A=-3x-37
Subtract 48 from 11 to get -37.
-A=-3x-37+7x
Add 7x to both sides.
-A=4x-37
Combine -3x and 7x to get 4x.
\frac{-A}{-1}=\frac{4x-37}{-1}
Divide both sides by -1.
A=\frac{4x-37}{-1}
Dividing by -1 undoes the multiplication by -1.
A=37-4x
Divide 4x-37 by -1.
x+11-4x=46-7x+2-A
Add 6 and 5 to get 11.
-3x+11=46-7x+2-A
Combine x and -4x to get -3x.
-3x+11=48-7x-A
Add 46 and 2 to get 48.
-3x+11+7x=48-A
Add 7x to both sides.
4x+11=48-A
Combine -3x and 7x to get 4x.
4x=48-A-11
Subtract 11 from both sides.
4x=37-A
Subtract 11 from 48 to get 37.
\frac{4x}{4}=\frac{37-A}{4}
Divide both sides by 4.
x=\frac{37-A}{4}
Dividing by 4 undoes the multiplication by 4.
