15x-3\left(18\times 5+1\right)=2\times 15+7
Multiply both sides of the equation by 15, the least common multiple of 5,15.
15x-3\left(90+1\right)=2\times 15+7
Multiply 18 and 5 to get 90.
15x-3\times 91=2\times 15+7
Add 90 and 1 to get 91.
15x-273=2\times 15+7
Multiply -3 and 91 to get -273.
15x-273=30+7
Multiply 2 and 15 to get 30.
15x-273=37
Add 30 and 7 to get 37.
15x=37+273
Add 273 to both sides.
15x=310
Add 37 and 273 to get 310.
x=\frac{310}{15}
Divide both sides by 15.
x=\frac{62}{3}
Reduce the fraction \frac{310}{15} to lowest terms by extracting and canceling out 5.
