f_{4}=4x-10-2
Combine 3x and x to get 4x.
f_{4}=4x-12
Subtract 2 from -10 to get -12.
f_{4}=4x-10-2
Combine 3x and x to get 4x.
f_{4}=4x-12
Subtract 2 from -10 to get -12.
4x-12=f_{4}
Swap sides so that all variable terms are on the left hand side.
4x=f_{4}+12
Add 12 to both sides.
\frac{4x}{4}=\frac{f_{4}+12}{4}
Divide both sides by 4.
x=\frac{f_{4}+12}{4}
Dividing by 4 undoes the multiplication by 4.
x=\frac{f_{4}}{4}+3
Divide f_{4}+12 by 4.
