4-8x=28
-8x=24
x=-3
2009-07-08 12:40 am
-8x=24
x=-3
2009-07-08 12:39 am

4-x-7x=28
4-8x=28
-8x=28-4
-8x=24
-x=24/8
-x=3
x=-3

4-x-7x=28

so 4-8x=28

so, -8x=28-4

so, -8x=24

so, 8x=-24

so, x=-24/8

so, x=-3

x=-3
2009-07-08 12:36 am
x=-3

4 - x - 7x = 28 <simplify terms with X>
4 - 8x = 28 <isolate the terms with X>
-8x = 24 <solve for X>
x = -3
2009-07-08 12:36 am
4-x-7x=28
-8x = 24
x = -3
