4x+12-5x-30=-x-18
4x+8x+3 = 12x+3
3x + (-2 + 4x) = -2 + 7x
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
x = -½
5x + 3 - 4 + 4x = 9x -1
16x
the answer to this is 4x + 57 (assuming that the 4x in the question is algebra)
4x^2 + 3
4x + 3 doesn't factor. It is in its simplest form.
(4x + 3)(4x + 3) (4x + 3)2
4x + 16 + 1 = 4x + 17 which cannot be factorised.
(4x+5)(4x+5)
8x + 15
4x + 20y
It is -4x - 4
4x plus 3 plus 2x is equivalent to expression 6x plus 3.
8x - 7y + 6
