Solve 90/17/20=x/15

$$\frac { \frac { 90 } { 17 } } { 20 } = \frac { x } { 15 }$$

Solve for x

$$x = \frac{135}{34} = 3\frac{33}{34} \approx 3.970588235$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 60, the least common multiple of 20,15.

$$3\times \frac{90}{17}=4x$$

Express 3\times \frac{90}{17} as a single fraction.

$$\frac{3\times 90}{17}=4x$$

Multiply 3 and 90 to get 270.

$$\frac{270}{17}=4x$$

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

$$4x=\frac{270}{17}$$

Divide both sides by 4.

$$x=\frac{\frac{270}{17}}{4}$$

Express \frac{\frac{270}{17}}{4} as a single fraction.

$$x=\frac{270}{17\times 4}$$

Multiply 17 and 4 to get 68.

$$x=\frac{270}{68}$$

Reduce the fraction \frac{270}{68} to lowest terms by extracting and canceling out 2.

$$x=\frac{135}{34}$$
