It could be: 2(x-8.5) = 2x-17
2x+17=6x-23 23+17=6x-2x 40=4x x=40 / 4 therefore x=10
12x-3=2x+17 10x-3=17 10x=20 x=2
2x = 17 then x = 8.5 2x+1=7 then x = 3 2x - 1 = 7 then x = 4 which is your problem
x=12
2x-3 = 17 2x = 17+3 2x = 20 x = 10
2x+17 = 4x-3 2x-4x = -3-17 -2x = -20 Answer: x =10
It could be: 2(x-8.5) = 2x-17
If: -2x+5 = -17 Then: x = 11
You did not state the operation: add or subtract. Is it 2x + 3 + 4 = 17? Is it 2x - 3 + 4 = 17?
-17-2x=6-x -23=x
2x-17=13 2x=30 x=15
2x+17=6x-23 23+17=6x-2x 40=4x x=40 / 4 therefore x=10
12x-3=2x+17 10x-3=17 10x=20 x=2
2x + 9 = -17 2x = -26 x = -13

If you mean: y = -2x+17 then the perpendicular slope line is 1/2 or 0.5
