Solve 3=12*150/150+(50+100)+(150+x)

$$3= \frac{ 12 \times 150 }{ 150+(50+100)+(150+x) }$$

Solve for x

$$x=150$$

Steps for Solving Linear Equation

Variable x cannot be equal to -450 since division by zero is not defined. Multiply both sides of the equation by x+450.

$$3\left(x+450\right)=12\times 150$$

Use the distributive property to multiply 3 by x+450.

$$3x+1350=12\times 150$$

Multiply 12 and 150 to get 1800.

$$3x+1350=1800$$

Subtract 1350 from both sides.

$$3x=1800-1350$$

Subtract 1350 from 1800 to get 450.

$$3x=450$$

Divide both sides by 3.

$$x=\frac{450}{3}$$

Divide 450 by 3 to get 150.

$$x=150$$
