Question

X in the equation 4(x-2)-3=9.

Answer 1

`x=5`

Explanation:

`4\left(x-2\right)-3=9`

`\mathrm{Add\:}3\mathrm{\:to\:both\:sides}`

`4\left(x-2\right)-3+3=9+3`

`\mathrm{Simplify}`

`4\left(x-2\right)=12`

`\mathrm{Divide\:both\:sides\:by\:}4`

`(4\left(x-2\right))/(4)=(12)/(4)`

`Simplify`

`x-2=3`

`\mathrm{Add\:}2\mathrm{\:to\:both\:sides}`

`x-2+2=3+2`

`Simplify`

`x=5`
