4x + 55 = 9x + 10 55 = 5x + 10 45 = 5x x = 9
5x+4x-10 = 35 9x = 35+10 9x = 45 x = 5
x=3 That wasn't hard at all. 5x-10=-7+4x -4x -4x _____________ x-10=-7 +10 +10 _____________ x=3
5x+2=x+10 5x-x=10-2 4x=8 x=2
5x+12 = 4x-88 x = -100
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
5x - 4x = 13 - 3 ie x = 10
4x + 55 = 9x + 10 55 = 5x + 10 45 = 5x x = 9
5x+4x-10 = 35 9x = 35+10 9x = 45 x = 5
x=3 That wasn't hard at all. 5x-10=-7+4x -4x -4x _____________ x-10=-7 +10 +10 _____________ x=3
5x+2=x+10 5x-x=10-2 4x=8 x=2
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
5x = 4x + 9 x = 9
