minus 4 plus 9 = 5, so 5x

If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7

5x = 4x + 9 x = 9

5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10

33

5x - 4x = 13 - 3 ie x = 10

4x - 10 + 5x = 719x = 81x = 9

5x - 4x = x

5x+3y

5x+1

5x+12 = 4x-88 x = -100

7x2 -4x -5x2 +2x = 2x2 -2x

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

5x + 3 = 4xSubtract 3 from each side:5x = 4x - 3Subtract 4x from each side:x = -3

-x2+2x

-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.

-4x + 3 = -5x + 3add 5x to each sidex + 3 = 3subtract three from each sidex = 0

x = 12

That equals x.

It is: 4X+X = 5X

4x + 55 = 9x + 10 55 = 5x + 10 45 = 5x x = 9

-4x +5x +4 =7 x + 4 = 7 x = 3

9x = 4x + 45 5x = 45x = 9

8x + 5x + 2x + 4x = 114 19x = 114 x = 6 then 5x + 3 = 5*6 + 3 = 33

3x - 5x + 4x = -2x +4x = 2x
