Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

Let the number = x

1/3x - 5= 2x             Multiply both sides by 3

1*x - 5*3 = 2x*3      Expand and collect like terms.

x - 15 = 6x                Subtract x from both sides

x - x - 15 = 6x-x        Collect like terms

- 15 = 5x                   Divide both sides by 5

-15/5 = 5x/5             do the Division

- 3 = x

Check

1/3(-3) - 5 = 2(-3)

-1 - 5 = - 6

- 6 = - 6

which checks.
