Question

An equation is shown 6x - 3 = 3x + 12 What is the solution to the equation ?
X=?

Answer 1

`x=5`

Explanation:

`6x-3=3x+12`

Add 3 to both sides:

• 
  `6x-3+3=3x+12+3`

• 
  `6x=3x+15`

Subtract 3x from both sides:

• 
  `6x-3x=3x+15-3x`

• 
  `3x=15`

Divide both sides by 3:

• 
  `(3x)/(3)=(15)/(3)`

• 
  `x=5`
