7t-5=x-11
Swap sides so that all variable terms are on the left hand side.
7t=x-11+5
Add 5 to both sides.
7t=x-6
Add -11 and 5 to get -6.
\frac{7t}{7}=\frac{x-6}{7}
Divide both sides by 7.
t=\frac{x-6}{7}
Dividing by 7 undoes the multiplication by 7.
x=7t-5+11
Add 11 to both sides.
x=7t+6
Add -5 and 11 to get 6.
