Question 65952
QUESTION:


2(x -3) - 3(x + 5) = 3(x - 2) - 7


ANSWER:


2(x -3) - 3(x + 5) = 3(x - 2) - 7


Remove parenthesis by multiplying....


==> 2*x - 2*3  - 3*x -3* 5 = 3*x - 3*2  - 7



==> 2x - 6 - 3x - 15 = 3x - 6 - 7


==> 2x - 3x -6 - 15 = 3x - 6 - 7


==> -1x - 21 = 3x - 13


Subtract 3x from both sides.....



==> -1x - 21 - 3x = 3x - 13 - 3x


==> -1x - 3x - 21 = - 13


==> -4x - 21 = -13


add 21 to both sides of the equation....


==> -4x - 21 + 21 = - 13 + 21


==> -4x = 8


divide both sides by -4


==> -4x/-4 = 8/-4


==> x = -2



So the solution is x= -2



Hope yopu understood.
