Question

Solve the equation 3(x-40)=21

Answer 1

`\boxed{x =47}`

Explanation:

`3(x-40)=21`

Step 1: Simplify both sides of the equation.

`3(x-40)=21`

`(3)^((x)) + (3) (-40) = 21` (Distribute)

`3x+ -120 = 21`

`3x - 120 = 21`

Step 2: Add 120 to both sides.

`3x - 120 + 120 = 21 + 120`

`3x = 141`

Step 3: Divide both sides by 3.

`(3x)/(3) = (141)/(3)`

`x = 47`
