Solve 36/12x40/A=12/1

$$\frac { 36 } { 12 } x \frac { 40 } { A } = \frac { 12 } { 1 }$$

Solve for x

$$x=\frac{A}{10}$$

$$A\neq 0$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 12A, the least common multiple of 12,A.

$$A\times 36x\times \frac{40}{A}=12A\times 12$$

Express A\times \frac{40}{A} as a single fraction.

$$\frac{A\times 40}{A}\times 36x=12A\times 12$$

Cancel out A in both numerator and denominator.

$$40\times 36x=12A\times 12$$

Multiply 12 and 12 to get 144.

$$40\times 36x=144A$$

Multiply 40 and 36 to get 1440.

$$1440x=144A$$

Divide both sides by 1440.

$$\frac{1440x}{1440}=\frac{144A}{1440}$$

Dividing by 1440 undoes the multiplication by 1440.

$$x=\frac{144A}{1440}$$

Divide 144A by 1440.

$$x=\frac{A}{10}$$

Solve for A

$$A=10x$$

$$x\neq 0$$
