2.3s + 4.6h = 4232
s + h = 1030
h = 1030 - s
2.3s + 4.6(1030 - s) = 4232
2.3s + 4738 - 4.6s = 4232
4738 - 4232 = 4.6s - 2.3s
506 = 2.3s
s = 220
h = 1030 - s
h = 1030 - 220 = 810

<h2>9x^4 - 6x^2 - 3x - 6</h2><h2 />
(9x^4-13x^3-x-7)+(7x^3-2x+1)
Sort the terms by their powers, as x's with the same powers can be added together:
9x^4
-13x^3 + 7x^3 = -6x^3
-x - 2x = -3x
-7 +1 = -6
