This expression can be simplified to: 2-6x
Not sure about slove, but to solve it: first combine like terms: 5x + 9 = 30 Then subtract 9 from both sides: 5x = 21 Finally, divide both sides by 5: x = 21/5 = 4.2
5x plus 3 does equal 3 plus 5x; commutative law.
-5x^2 - 55x - 120
5x + 23x + 10 = 28x + 10( ? ? ? )

-10x + 5x = -5x
x=6
No
5x+5x-10 10x-10 is the only answer you can get from this
10x - 5x + 5x = 10x
It is: 5x
2x plus 5x simplified is 7x.
-5x^2 - 55x - 120
5x+2x=7x2x + 5x = 7x
