Answer:
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.
