Solve x+x+1+x+2+x+3+x+4=75

$$x+x+1+x+2+x+3+x+4 = 75$$

Solve for x

$$x=13$$

Steps for Solving Linear Equation

Combine x and x to get 2x.

$$2x+1+x+2+x+3+x+4=75$$

Combine 2x and x to get 3x.

$$3x+1+2+x+3+x+4=75$$

Add 1 and 2 to get 3.

$$3x+3+x+3+x+4=75$$

Combine 3x and x to get 4x.

$$4x+3+3+x+4=75$$

Add 3 and 3 to get 6.

$$4x+6+x+4=75$$

Combine 4x and x to get 5x.

$$5x+6+4=75$$

Add 6 and 4 to get 10.

$$5x+10=75$$

Subtract 10 from both sides.

$$5x=75-10$$

Subtract 10 from 75 to get 65.

$$5x=65$$

Divide both sides by 5.

$$x=\frac{65}{5}$$

Divide 65 by 5 to get 13.

$$x=13$$
