Answer:

x= 42/5

alternative forms:

x=8 2/5

x=8.4

Explanation:

Start with x-1/6x=7

Multiply both sides by 6 to get 6x-x=42

combine like terms (the Xs) to get 5x (6x-x is 5x)

5x=42

divide both sides by 5 to get x=42/5

Answer:

x = 42/5

Explanation:

x -1/6x=7

Get a common denominator

6/6x - 1/6 x = 7

5/6x = 7

Multiply each side by 6/5 to isolate x

6/5 * 5/6x = 6/5*7

x = 42/5
