Solve 15=1/2x+3x+1x

$$15= \frac{ 1 }{ 2 } x+3x+1x$$

Solve for x

$$x = \frac{10}{3} = 3\frac{1}{3} \approx 3.333333333$$

Steps for Solving Linear Equation

Combine \frac{1}{2}x and 3x to get \frac{7}{2}x.

$$15=\frac{7}{2}x+1x$$

Combine \frac{7}{2}x and 1x to get \frac{9}{2}x.

$$15=\frac{9}{2}x$$

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

$$\frac{9}{2}x=15$$

Multiply both sides by \frac{2}{9}, the reciprocal of \frac{9}{2}.

$$x=15\times \frac{2}{9}$$

Express 15\times \frac{2}{9} as a single fraction.

$$x=\frac{15\times 2}{9}$$

Multiply 15 and 2 to get 30.

$$x=\frac{30}{9}$$

Reduce the fraction \frac{30}{9} to lowest terms by extracting and canceling out 3.

$$x=\frac{10}{3}$$
