22+22+28+28=100.
it equals 28
3x + 7 = -4x + 28 implies 7x + 7 = 28
That equals 28

22+22+28+28=100.
it equals 28
it is 28
3x + 7 = -4x + 28 implies 7x + 7 = 28
7 + 6 = 113 ---> 7+6=13 and 7-6=1 so write it 1139 + 1 = 810 ---> 9+1=10 and 9-1=8 so write it 8105 + 3 = 28 ---> 5+3=8 and 5-3=2 so write it 289 + 6 = 315 ---> 9+6=15 and 9-6=3 so write it 315Then process in the same manner,7 + 2 =? ----> 7+2=9 and 7-2=5 so you write it as 59! 59
That equals 28
25 + 28 + 29 = 82

28 + 42 = 70
18 + 10 + 28 + 10 = 66
