Just like any other equations with one variable:

X + X/2 -4 = X/4

Move variables to one side, and constants to other.

X + X/2 - X/4 = 4

Multiply both sides by 4

4X + 2X - x = 16

5X = 16

X = 16/ 5 = 3 1/5 = 3.2

x + x/2 - 4 = x/4

get rid of fractions by finding a common denominator which is 4

multiply each term by 4

(4)x + (4)x/2 - (4)4=(4)x/4

4x + 2x - 16 = x

combine like terms

6x-16=x

add 16 to both sides

6x-16+16=x+16

6x=x+16

subtract x from both sides

6x-x=x-x+16

5x=16

divide both sides by 5

5x/5=16/5

x=16/5

x + x/2 - 4 = x/4

x + x/2 - x/4 = 4

4x/4 + 2x/4 - x/4 = 4

5x/4 = 4

multiply both sides by 4:

5x = 16

divide both sides by 5:
