Solve (120divx)div3=40div3

$$(120 \div x) \div 3=40 \div 3$$

Solve for x

$$x=3$$

Steps for Solving Linear Equation

Multiply both sides by 3.

$$\frac{120}{x}=\frac{40}{3}\times 3$$

Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 3x, the least common multiple of x,3.

$$3\times 120=\frac{40}{3}\times 3\times 3x$$

Multiply 3 and 120 to get 360.

$$360=\frac{40}{3}\times 3\times 3x$$

Cancel out 3 and 3.

$$360=40\times 3x$$

Multiply 40 and 3 to get 120.

$$360=120x$$

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

$$120x=360$$

Divide both sides by 120.

$$x=\frac{360}{120}$$

Divide 360 by 120 to get 3.

$$x=3$$
