Question 66471: 2(x-3)-3(x+5)=3(x-2)-7
Answer by ankor@dixie-net.com(22740)   (Show Source):
You can put this solution on YOUR website! 2(x-3) - 3(x+5) = 3(x-2) - 7
:
Mult what's inside the brackets, change the sign when the multiplier is negative
2x - 6 - 3x - 15 = 3x - 6 - 7
:
Perform the operations necessary to get the variables (x) on left, numbers on the
right, then solve for x:
2x - 3x - 3x = - 6 - 7 + 6 + 15
:
-4x = +8
:
x = +8/-4
:
x = -2
:
:
Check in original equation, substitute -2 for x
2(x-3) - 3(x+5) = 3(x-2) - 7
2(-2-3) - 3(-2+5) = 3(-2-2) - 7
2(-5) - 3(+3) = 3(-4) - 7
-10 - 9 = -12 - 7
-19 = -19
