3\times 36+7=36x+3\left(1\times 12+11\right)
Multiply both sides of the equation by 36, the least common multiple of 36,12.
108+7=36x+3\left(1\times 12+11\right)
Multiply 3 and 36 to get 108.
115=36x+3\left(1\times 12+11\right)
Add 108 and 7 to get 115.
115=36x+3\left(12+11\right)
Multiply 1 and 12 to get 12.
115=36x+3\times 23
Add 12 and 11 to get 23.
115=36x+69
Multiply 3 and 23 to get 69.
36x+69=115
Swap sides so that all variable terms are on the left hand side.
36x=115-69
Subtract 69 from both sides.
36x=46
Subtract 69 from 115 to get 46.
x=\frac{46}{36}
Divide both sides by 36.
x=\frac{23}{18}
Reduce the fraction \frac{46}{36} to lowest terms by extracting and canceling out 2.
