If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
4x - 3 - 5x + 7 = 6 4x - 5x = 3 - 7 + 6 -1x = 2 x = -2
4x-7=5x-2 x=-5
We start with 4x + 8 = 5x -5. Subtract 4x from both sides of the equation, which gives us 8 = x - 5. Add 5 to both sides of the equation, this gives us 13 = x. Problem solved.
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
5x = 4x + 9 x = 9

x + 3 + 4x = 13 3 +5x = 13 -- combine like terms 5x = 10 -- subtract 3 x = 2 --- divide by 5 "x" equals two
4x + 13 = 76 - 5x Add 5x to both sides: 9x + 13 = 76 Subtract 13 from both sides: 9x = 63 Divide both sides by 9: x = 7
4x - 10 + 5x = 719x = 81x = 9
4x-3+2x-x = 10 Collect the like terms; 5x-3 = 10 5x = 13 x = 13/5
5x+12 = 4x-88 x = -100

5x - 18 = 4x + 7Add 18 to each side:5x = 4x + 25Subtract 4x from each side:x = 25
