-8x+12=-3
-8x=-15
x=15/8

Gee, you almost had x=2. Try again.

-4(2x-3)=-8+5?
-4 x 2 x X minus -4 x -3 = -8 + 5
-4 x 2 is -8 and -8 + 5 is negative 3.
-8 x X minus -4 x -3 = -3
-4 times -3 is - - 12, which is + + 12.
-8X + 12 = -3
Get the X by itself.
-8X = -3 - 12 (I subtracted 12 on both sides)
-8X = -15
+8X = +15
X = 15/8
15 / 8 is also 7 + 8 divided by 8
So 8/8 + 7/8 is 15/8
And 8/8 is 1/1 or 2/2 or 3/3 or 4/4 or ONE.
So 15/8 is 1 plus 7/8.
7/8 is a little smaller than 1.
1 and 7/8 is a little smaller than 2.

-4(2x-3)=-8+5 distribute -4 & combine like terms
-8x+12=-3 subtract 12 from each side
-8x=-15 divide both sides by -8
x=15/8=1 7/8 or 1.875

The right side is easy enough to simplify:
-4(2x-3)=-8+5
-4(2x-3)= -3

Now divide both sidex by -4, add 3 to both sides, and finally divide by 2. This will get x by itself.

(2x-3)= -3/-4
(2x-3)= 3/4
2x = 3/4 + 3
2x = 3/4 + 12/4
2x = 15/4
x = 15/8

first of all open up your brackets... which will give
-8x + 12 = -8 + 5
-8x = -15
x = 15 / 8

-8x+12=-8+5
x-12/8=1-5/8
x-12/8=3/8
x=15/8
x=1 and 7/8
