10x+5\times 3x+2\times 4x=330
Multiply both sides of the equation by 10, the least common multiple of 2,5.
10x+15x+2\times 4x=330
Multiply 5 and 3 to get 15.
25x+2\times 4x=330
Combine 10x and 15x to get 25x.
25x+8x=330
Multiply 2 and 4 to get 8.
33x=330
Combine 25x and 8x to get 33x.
x=\frac{330}{33}
Divide both sides by 33.
x=10
Divide 330 by 33 to get 10.
