How to solve 3x = 20/7 - x is

1. Factor the equation (x + 2)(x + 3) = 0. 2. Set each factor equal to zero: x + 2 = 0 and x + 3 = 0. 3. Solve for x: x = -2 and x = -3.

Question

$$3 x = \frac { 20 } { 7 } - x$$

Solve for x

$x=\frac{5}{7}\approx 0.714285714$

Steps for Solving Linear Equation

Add $x$ to both sides.

$$3x+x=\frac{20}{7}$$

Combine $3x$ and $x$ to get $4x$.

$$4x=\frac{20}{7}$$

Divide both sides by $4$.

$$x=\frac{\frac{20}{7}}{4}$$

Express $\frac{\frac{20}{7}}{4}$ as a single fraction.

$$x=\frac{20}{7\times 4}$$

Multiply $7$ and $4$ to get $28$.

$$x=\frac{20}{28}$$

Reduce the fraction $\frac{20}{28}$ to lowest terms by extracting and canceling out $4$.

$$x=\frac{5}{7}$$
