Hello!
9x + 4 + x = 54 <=>
<=> 9x + x + 4 = 54 <=>
<=> 10x + 4 = 54 <=>
<=> 10x = 54 - 4 <=>
<=> 10x = 50 <=>
<=> x = 50 : 10 <=>
<=> x = 5 => 9 × 5 + 4 + 5 = 54
Good luck! :)
Combine the like terms.
-3x^2 - (-x^2) = -3x^2 + x^2 = -2x^2
4x - (-4x) = 4x +4x = 8x
The difference would be: -2x^2 + 8x - 1
