Find Y. I need to check if my answers are correct for these, you don't have to add a explanation, thank you so much to whoever does this. 1 point for each question :D! 1.) -2(x + 3y) = 18

2.) 5x + 10 = 10y

3.) 5y + 8 = 2y – 3x + 5

4.) 3y = 15x – 12

5.) x + 5y – 10 = 2x

6.) 8x – 4y = -4

7.) 9x + 3y = 3

8.) 5(x + y) = 20 + 3x

9.) 3y – 21 = 12x

10.) 2x + 3y = 3

11.) x – 2y = 4

12.) -2x - y = -3
