Solve 7+x+2x+4=55/3

$$7+x+2x+4= \frac{ 55 }{ 3 }$$

Solve for x

$$x = \frac{22}{9} = 2\frac{4}{9} \approx 2.444444444$$

Steps for Solving Linear Equation

Combine x and 2x to get 3x.

$$7+3x+4=\frac{55}{3}$$

Add 7 and 4 to get 11.

$$11+3x=\frac{55}{3}$$

Subtract 11 from both sides.

$$3x=\frac{55}{3}-11$$

Convert 11 to fraction \frac{33}{3}.

$$3x=\frac{55}{3}-\frac{33}{3}$$

Since \frac{55}{3} and \frac{33}{3} have the same denominator, subtract them by subtracting their numerators.

$$3x=\frac{55-33}{3}$$

Subtract 33 from 55 to get 22.

$$3x=\frac{22}{3}$$

Divide both sides by 3.

$$x=\frac{\frac{22}{3}}{3}$$

Express \frac{\frac{22}{3}}{3} as a single fraction.

$$x=\frac{22}{3\times 3}$$

Multiply 3 and 3 to get 9.

$$x=\frac{22}{9}$$
