2 + 2 + 78 = 82
The answer is 97.
78+78-:(85)/(78)+7,879=1405
55 + 82 + 92 + 78 + 100 + 96 + 78 = 581
3.14 + 2.18+ 1.78 = 7.10
2 + 2 + 78 = 82
The answer is 97.
It is: (85*2)+(78*8) = 794
78+78-:(85)/(78)+7,879=1405
78 + 89 + 167 + 897 + 78 = 1309
55 + 82 + 92 + 78 + 100 + 96 + 78 = 581
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 = 78
78 + 78 = 156

3.14 + 2.18+ 1.78 = 7.10
7.8 + 12 = 19.8
2x + 89 = 78 Therefore, 2x = 78 - 89 x = -11/2 x = -5.5
