The expression (9x 7)-(x 3) can be simplified as follows: (9x - 7) - (x - 3) = 9x - 7 - x + 3 = 8x - 4
If: 9x+7 = 6x+25 Then: x = 6
4x+3=9x-4+4 +44x+7=9x-4x -4x7=5x-------57/5=1.41.4=x
4x+7=9x+7 -5x=0 x=0
2x + 3 = 9x Subtract 2x from both sides: 3 = 7x Divide both sides by 7: 3/7 = x
9x+4 =x-7 8x=-3 x=-3/8
x+5+3x-7+9x+3-4x Collect like terms: 9x+1
x + 5 + 3x - 7 + 9x + 3 - 4x Switch the like numbers closer to make the equation easier. x + 3x + 9x - 4x + 5 - 7 + 3 However this is an unsolvable as it isn't an equation. An equation needs an equals sign, for example: x + 3x + 9x - 4x + 5 - 7 + 3 = 0, or x + 3x + 9x - 4x + 5 - 7 + 3 = 10 If it is the former then the answer is 9x = -1 Thus x = -1/9
2x+3=9x 3=9x-2x 3=7x x=3/7
The expression (9x 7)-(x 3) can be simplified as follows: (9x - 7) - (x - 3) = 9x - 7 - x + 3 = 8x - 4
2x+3=9x-2x -2x3=7x/7 /73/7=x
If: 9x+7 = 6x+25 Then: x = 6
4x+3=9x-4+4 +44x+7=9x-4x -4x7=5x-------57/5=1.41.4=x
7 plus 7x--2x plus 3 is: 7 + 7x + 2x + 3 = 0 9x + 10 = 0 9x = -10 x = -10/9 = -1 1/9
4x+7=9x+7 -5x=0 x=0
2x + 3 = 9x Subtract 2x from both sides: 3 = 7x Divide both sides by 7: 3/7 = x
(9x2 + 7)(9x2 - 7) = 81x4 - 49
