Solve 4=260000/frac{x+x+20000{2}}

$$4 = \frac { 260000 } { \frac { x + x + 20000 } { 2 } }$$

Solve for x

$$x=55000$$

Steps for Solving Linear Equation

Divide 260000 by \frac{x+x+20000}{2} by multiplying 260000 by the reciprocal of \frac{x+x+20000}{2}.

$$4=\frac{260000\times 2}{x+x+20000}$$

Multiply 260000 and 2 to get 520000.

$$4=\frac{520000}{x+x+20000}$$

Combine x and x to get 2x.

$$4=\frac{520000}{2x+20000}$$

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

$$\frac{520000}{2x+20000}=4$$

Variable x cannot be equal to -10000 since division by zero is not defined. Multiply both sides of the equation by 2\left(x+10000\right).

$$520000=8\left(x+10000\right)$$

Divide both sides by 8.

$$\frac{520000}{8}=x+10000$$

Divide 520000 by 8 to get 65000.

$$65000=x+10000$$

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

$$x+10000=65000$$

Subtract 10000 from both sides.

$$x=65000-10000$$

Subtract 10000 from 65000 to get 55000.

$$x=55000$$
