2\times 7=20x\times \frac{3}{20}+20x\times 2
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 20x, the least common multiple of 10x,20.
14=20x\times \frac{3}{20}+20x\times 2
Multiply 2 and 7 to get 14.
14=3x+20x\times 2
Multiply 20 and \frac{3}{20} to get 3.
14=3x+40x
Multiply 20 and 2 to get 40.
14=43x
Combine 3x and 40x to get 43x.
43x=14
Swap sides so that all variable terms are on the left hand side.
x=\frac{14}{43}
Divide both sides by 43.
