7. 8x-40=2x+2 4x-20=1x+1 3x-21=0 3x=21 therefore x=7
6-3x = 5x-10x+2 4 = 8x-10x 4 = -2x x = -2
0. 7 - 3x = 5x + 13 1. 7 - 8x = 13 2. -8x = 5 3. x = -5/8.
Balance the equation.8x + 2 = 50 + 3x8x - 3x + 2 = 505x + 2 = 505x = 50 - 25x = 48x = 9.6... are you sure that you asked the question correctly? Normally, basic Algebra works out to whole numbers....
It is the same as 8x+2 when simplified
