solve this equation for x: 0.5(5-7x)=8-(4x+6)
0.5(5-7x)=8-(4x+6) note.......0.5 = 1/2
(1/2) ( 5 - 7x) = 8 - 4x - 6
(1/2) (5 - 7x) = 2 - 4x multipy through by 2
5 - 7x = 4 - 8x add 8x to both sides.......subtract 5 from both sides
x = -1
0.5(5-7x0)=8-(4x+6)
2.5-3.5x=8-4x-6
-2.5 -2.5
------------------
-3.5x=5.5-4x-6
-3.5x=-0.5-4x
+0.5 =0.5
--------------
-3.5x+0.5=-4x
-3.5x -3.5x
-------------------
0.5=-0.5x
--- ------
-0.5 -0.5
-1=x
