10.

Write in standard form.
2x - 8 = -3y + 2

2x + 3y = 10

2x - 3y = 10

2x + 3y = -6

2x - 3y = -6

11.

Write an equation in Standard Form.
A store sells t-shirts for $12 each and sweatshirts for $15 each. You plan to spend $120 on t-shirts and sweatshirts.

12x + 15y = 120

12 + 15y = 2x

12x + 15 = 120
