5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
If your equation is 5x-2=4x+4 Then this is how you solve it... 5x-2=4x+4 5x-2+2=4x+4+2 5x=4x+6 5x-4x=4x-4x+6 x=6 Your x=6
5x-2x-3x+4x = (5-2-3+4)x = 4x
8x + 5x + 2x + 4x = 114 19x = 114 x = 6 then 5x + 3 = 5*6 + 3 = 33
5x + (3y-x) + (10-2y) = 5x + 3y - x + 10 -2y = 5x - x + 3y - 2y + 10 = 4x + y +10
9 + 5x = -4x + 63 9 + 9x = 63 9x = 54 9x/9 = 54/9 x = 6
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
2x + 4x - x = 5x
5x = 4x + 9 x = 9
If your equation is 5x-2=4x+4 Then this is how you solve it... 5x-2=4x+4 5x-2+2=4x+4+2 5x=4x+6 5x-4x=4x-4x+6 x=6 Your x=6
5x+12 = 4x-88 x = -100
4x+12-5x-30=-x-18
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
5x - 4x = 13 - 3 ie x = 10
4x-9(x plus 1)7-5x?
4x + 5 < 5x + 3 5 < x + 3 x > 2
