30x\times \frac{1}{2}+6\times 2-10=6\times 7+30x\times \frac{1}{6}+30x\left(-\frac{1}{3}\right)
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 30x, the least common multiple of 2,5x,3x,6,3.
15x+6\times 2-10=6\times 7+30x\times \frac{1}{6}+30x\left(-\frac{1}{3}\right)
Multiply 30 and \frac{1}{2} to get 15.
15x+12-10=6\times 7+30x\times \frac{1}{6}+30x\left(-\frac{1}{3}\right)
Multiply 6 and 2 to get 12.
15x+2=6\times 7+30x\times \frac{1}{6}+30x\left(-\frac{1}{3}\right)
Subtract 10 from 12 to get 2.
15x+2=42+30x\times \frac{1}{6}+30x\left(-\frac{1}{3}\right)
Multiply 6 and 7 to get 42.
15x+2=42+5x+30x\left(-\frac{1}{3}\right)
Multiply 30 and \frac{1}{6} to get 5.
15x+2=42+5x-10x
Multiply 30 and -\frac{1}{3} to get -10.
15x+2=42-5x
Combine 5x and -10x to get -5x.
15x+2+5x=42
Add 5x to both sides.
20x+2=42
Combine 15x and 5x to get 20x.
20x=42-2
Subtract 2 from both sides.
20x=40
Subtract 2 from 42 to get 40.
x=\frac{40}{20}
Divide both sides by 20.
x=2
Divide 40 by 20 to get 2.
