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
x = 42/5
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
