Simplify: 10x – 6xy + 3y – 5x + xy - 5y2
10x – 6xy + 3y – 5x + xy – 5y2
-5y2 + 3y + (-6xy + xy) + (10x – 5x)
-5y2 + 3y + (-5xy) + 5x
or -5y2 + 3y – 5xy + 5x
Solve for H:
- 180 + H = 235
- 180 + H = 235
H = 235 + 180 = 415
H = 415

If Jayden wanted to get a video game for 78 dollars, tax included, and he already has saved up 52 dollars - How much is he missing to buy his game? Write an equation and then solve.
J + 52 = 78
J = 78 - 52 = 26
J = 26 - He is missing 26 dollars
