Solve 4x+2/7x=15

$$4 x + \frac { 2 } { 7 } x = 15$$

Solve for x

$$x = \frac{7}{2} = 3\frac{1}{2} = 3.5$$

Steps for Solving Linear Equation

Combine 4x and \frac{2}{7}x to get \frac{30}{7}x.

$$\frac{30}{7}x=15$$

Multiply both sides by \frac{7}{30}, the reciprocal of \frac{30}{7}.

$$x=15\times \frac{7}{30}$$

Express 15\times \frac{7}{30} as a single fraction.

$$x=\frac{15\times 7}{30}$$

Multiply 15 and 7 to get 105.

$$x=\frac{105}{30}$$

Reduce the fraction \frac{105}{30} to lowest terms by extracting and canceling out 15.

$$x=\frac{7}{2}$$
