Solve 4x+2/5x=70*4

$$4 x + \frac { 2 } { 5 } x = 70 \cdot 4$$

Solve for x

$$x = \frac{700}{11} = 63\frac{7}{11} \approx 63.636363636$$

Steps for Solving Linear Equation

Combine 4x and \frac{2}{5}x to get \frac{22}{5}x.

$$\frac{22}{5}x=70\times 4$$

Multiply 70 and 4 to get 280.

$$\frac{22}{5}x=280$$

Multiply both sides by \frac{5}{22}, the reciprocal of \frac{22}{5}.

$$x=280\times \frac{5}{22}$$

Express 280\times \frac{5}{22} as a single fraction.

$$x=\frac{280\times 5}{22}$$

Multiply 280 and 5 to get 1400.

$$x=\frac{1400}{22}$$

Reduce the fraction \frac{1400}{22} to lowest terms by extracting and canceling out 2.

$$x=\frac{700}{11}$$
