10 + 8v - 3v = 10 + 5v

18 + 10 + 28 + 10 = 66
m = -10 !
It is: 12+(-4)-(-10) = 18
10 + 8v - 3v = 10 + 5v

18 + 10 + 28 + 10 = 66
few errors in your title: 2 plus 4 = 6 6 plus 9 = 15 10 plus 25 = 35 18 + 81 = 99
18 + 10 + 20 + 30 + 15 + 50= 143
4y + 10 = -18 4y = -28 y = -7
8.
m = -10 !
It is: 12+(-4)-(-10) = 18
3 times 6 is 18 2 times 5 is 10 18 plus 10 is 28
x + 10 = 18 18 - 10 = x 18 -10 = 8 x = 8
