Solve 3=12*150/150+(50+x)

$$3= \frac{ 12 \times 150 }{ 150+(50+x) }$$

Solve for x

$$x=400$$

Steps for Solving Linear Equation

Variable x cannot be equal to -200 since division by zero is not defined. Multiply both sides of the equation by x+200.

$$3\left(x+200\right)=12\times 150$$

Use the distributive property to multiply 3 by x+200.

$$3x+600=12\times 150$$

Multiply 12 and 150 to get 1800.

$$3x+600=1800$$

Subtract 600 from both sides.

$$3x=1800-600$$

Subtract 600 from 1800 to get 1200.

$$3x=1200$$

Divide both sides by 3.

$$x=\frac{1200}{3}$$

Divide 1200 by 3 to get 400.

$$x=400$$
