2x
2x plus 5x simplified is 7x.
-2x^4+16 +2x^4+9-3x^5=-3x^5+25. There is no "answer" because there is no equation.
(2x+3)(2x+4)
(2x+5)(2x+1)
8x-4
3x + 2x - 8x + 2x = -x
x=1
It is 2x+(-2x) = 0
2x + - 2x = 0 (zero) Remember when you have two opposite signs, treat it as negative (-). Also the 'x' is an unknown but fixed amount, so the 'x' in '2x' could be '3', so the 'x' in '-2x' is ALSO '3'. Hence 2(3) + - 2(3) = 6 - 6 = 0 NB For mixed signs# = + = - = - = +
4
-2x + 6 + 22 = -2x + 28

6 + 2x + 5 = 11 + 2x
2x
It can be simplified to: 2x+33
it equals 13X.
