10x + 7 = 4x + 49 6x + 7 = 49 6x = 42 x = 6
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
If you mean 49+6 = 4x-7 then the value of x is 15.5
3x + 9
4x + 2 = 3x + 9 x + 2 = 9 x = 7
5x = 4x + 9 x = 9
4x+5 = -9 4x = -9-5 4x = -14 x = -3.5
If you mean: x+4x--9 = x+1 then 4x = -8 and x = -2
It is an equation and the value of x is 6
4x3 + 16x2 - 180x = 4x(x2 + 4x - 45) = 4x(x + 9)(x - 5)
4x-9(x plus 1)7-5x?
4x+9=25 4x=16 x=4
