Question

What is the value of x if 5x=12x-20

Answer 1

`x = (20)/(7) \\ \\ x = 2 (6)/(7)`.

Explanation:

`5x = 12x - 20`

Collect like terms and simplify

`5x - 12x = - 20 \\ - 7x = - 20`

Divide both sides of the equation by -7

`( - 7x)/( - 7) = ( - 20)/( - 7)`

Simplify

`x = (20)/(7) \\ \\ x = 2 (6)/(7)`

Answer 2

x = 20/7

Explanation:

5x = 12x - 20

5x - 12x = -20

-7x = -20

x = 20/7
