Question

How do you solve `(x+5) - (2x+8) = 3(x-3)`?

Answer 1

`x = 3/2`

Explanation:

Rewrite the equation without brackets.

thus : x + 5 - 2x - 8 = 3x - 9

now collect x terms to the left and numbers to the right.
Remember to change the 'signs' of the terms as you move them from one side of the equation to the other.

hence : x - 2x - 3x = -9 + 8 - 5 → -4x = -6

divide both sides by -4

`rArr cancel(-4) x/cancel(-4) =( -6)/-4 = 6/4 = 3/2`
