30x-5=6\left(2\times 5+2\right)+15\left(2\times 2+1\right)
Multiply both sides of the equation by 30, the least common multiple of 6,5,2.
30x-5=6\left(10+2\right)+15\left(2\times 2+1\right)
Multiply 2 and 5 to get 10.
30x-5=6\times 12+15\left(2\times 2+1\right)
Add 10 and 2 to get 12.
30x-5=72+15\left(2\times 2+1\right)
Multiply 6 and 12 to get 72.
30x-5=72+15\left(4+1\right)
Multiply 2 and 2 to get 4.
30x-5=72+15\times 5
Add 4 and 1 to get 5.
30x-5=72+75
Multiply 15 and 5 to get 75.
30x-5=147
Add 72 and 75 to get 147.
30x=147+5
Add 5 to both sides.
30x=152
Add 147 and 5 to get 152.
x=\frac{152}{30}
Divide both sides by 30.
x=\frac{76}{15}
Reduce the fraction \frac{152}{30} to lowest terms by extracting and canceling out 2.
