Question

Slove the equation 3(x - 1) = 2x + 9

Answer 1

the expression that we have is:

$3(x-1)=2x+9$

the first thing we can do, is to distribute the 3 into the parenthesis:

$3x-3=2x+9$

now, we can pass all the terms with x to the left of the equation, and constants to the right of the equation:

$3x-2x=9+3$

and now we can solve the ecuation for x

$x=12$
