Solve 600/600+x=0.8

$$\frac { 600 } { 600 + x } = 0.8$$

Solve for x

$$x=150$$

Steps for Solving Linear Equation

Variable x cannot be equal to -600 since division by zero is not defined. Multiply both sides of the equation by x+600.

$$600=0.8\left(x+600\right)$$

Use the distributive property to multiply 0.8 by x+600.

$$600=0.8x+480$$

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

$$0.8x+480=600$$

Subtract 480 from both sides.

$$0.8x=600-480$$

Subtract 480 from 600 to get 120.

$$0.8x=120$$

Divide both sides by 0.8.

$$x=\frac{120}{0.8}$$

Expand \frac{120}{0.8} by multiplying both numerator and the denominator by 10.

$$x=\frac{1200}{8}$$

Divide 1200 by 8 to get 150.

$$x=150$$
