Solve 21000/2x-4000/x=10

$$\frac { 21000 } { 2 x } - \frac { 4000 } { x } = 10$$

Solve for x

$$x=650$$

Steps for Solving Linear Equation

Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 2x, the least common multiple of 2x,x.

$$21000-2\times 4000=20x$$

Multiply -2 and 4000 to get -8000.

$$21000-8000=20x$$

Subtract 8000 from 21000 to get 13000.

$$13000=20x$$

Swap sides so that all variable terms are on the left hand side.

$$20x=13000$$

Divide both sides by 20.

$$x=\frac{13000}{20}$$

Divide 13000 by 20 to get 650.

$$x=650$$
