15 - 7 + 6 is 14
8 plus 7 is 15. 15 plus 6 is 21. :)
-12 + 6 - 10 - 6 +15 = -7
7 + (2 x 15) - 6 = 31
If that is: 15+(26-6)*(7-84) then it works out as -1525
(-7 x -3) + (-6) = 21 - 6 = 15
-3 + -7 + 5 + -4 + -6 = -15
15 of course.
3x+7=15 -7 -7 3x=6 (Divide) 3 3 x=2 Check it: 3(2)+7=15 6+7=15 15=15 :D
It can be simplified to 8.7x - 7
The answer is 39.7 + 8 = 15 + 4 = 19 + 7 = 26 + 5 = 31+ 6 = 37 + 2 =39
8
No.No.No.No.
