BY STEP! sorry ment to put it in the question
2007-09-06 16:49:26 · update #1
and 4x - 3 = 7x +8 - 8x in step too please
2007-09-06 16:50:59 · update #2
-7 - a = -6
(add 7 on both sides)
-a = 1
a = -1
_______________________________________________
4x - 3 = 7x +8 - 8x
(Group the x together)
4x - 3 = -x + 8
(Add x on both sides)
5x - 3 = 8
(Add 3 to both sides)
5x = 11
x = 11/5
..i think it should be done like this..

-7 -a = -6 (add 6 both sides )
-7 +6 -a = 0 (add a both sides )
-7 +6 = a
-1 = a
whatever is done to both sides of an equation doesnt change the result
4x - 3 = 7x +8 - 8x
4x -3 -8 =7x -8x
-3 -8 = 7x -8x -4x
-11 = -5x
x = 11/5

-7 -a = -6
=> a = -7 + 6 = -1
=> a = -1

-7 -a = -6
-a = 7 - 6
-a = 1 (-)
a = - 1
and
4x -3 = 7x + 8 - 8x
4x - 7x + 8x = 8 + 3
5x = 11
x = 11/5

-7 - a = -6
a = -1
4x - 3 = 7x +8 - 8x
5x = 11
x = 11/5 = 2 1/5

-7 - a = -6
- 7 + 6 = a
a = -1

Add 7 to both sides:
-a = 1
Negate both sides:
a = -1

-a=-6+7
-a=1
a=-1
4x-3=7x+8-8x
4x-3=x+8
4x-x=8+3
3x=11
x=11/3
