Solve 15/5+5/x==20

$$\frac{ 15 }{ 5 } + \frac{ 5 }{ x } ==20$$

Solve for x

$$x=\frac{5}{17}\approx 0.294117647$$

Steps for Solving Linear Equation

Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 5x, the least common multiple of 5,x.

$$x\times 15+5\times 5=100x$$

Multiply 5 and 5 to get 25.

$$x\times 15+25=100x$$

Subtract 100x from both sides.

$$x\times 15+25-100x=0$$

Combine x\times 15 and -100x to get -85x.

$$-85x+25=0$$

Subtract 25 from both sides. Anything subtracted from zero gives its negation.

$$-85x=-25$$

Divide both sides by -85.

$$x=\frac{-25}{-85}$$

Reduce the fraction \frac{-25}{-85} to lowest terms by extracting and canceling out -5.

$$x=\frac{5}{17}$$
