18 + 10 + 20 + 30 + 15 + 50= 143
2+14=16
4y + 10 = -18 4y = -28 y = -7
20 = 400
3 + 3 = 6 6 x 3 = 18 18 - 3 = 15 15 + 3 = 18
8 + 5y = 18 Therefore, 5y = 10 y = 10/5 y = 2
few errors in your title: 2 plus 4 = 6 6 plus 9 = 15 10 plus 25 = 35 18 + 81 = 99
18 + 10 + 28 + 10 = 66
2+14=16
57 - (24 plus 15) = 18
4y + 10 = -18 4y = -28 y = -7

20 = 400
8.
m = -10 !
It is: 12+(-4)-(-10) = 18
3 times 6 is 18 2 times 5 is 10 18 plus 10 is 28
