2x+4+7x-4 is the same as 9x
7 plus 7x--2x plus 3 is: 7 + 7x + 2x + 3 = 0 9x + 10 = 0 9x = -10 x = -10/9 = -1 1/9
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
2x plus 5x simplified is 7x.
2x2 + 7x - 15 = (2x - 3)(x + 5)
It is 9x
5x+2x=7x2x + 5x = 7x
2x + ? = 9x9x - 2x = 7xso...2x + 7x = 9x
You would factor 2x2 + 7x + 6 into (2x + 3) (x+2)
7x + 3
13x
(3x - 1) + 7 = (7x - 2x) + x3x - 1 + 7 = 7x - 2x + x3x + 6 = 6x6 = 3xx = 6/3 = 2
