-108
1
It is: x-1+4+7x-3 = 8x simplified
37
It is: 12/5 times 5/8 = 60/40 = 3/2 simplified or as 1.5
If you multiplied all the terms by y2, you could simplify this to -3y3.
1/2 x -6 = -3
3+2*A+B*4/2-4 = 3 + 2A + 2B - 4 = 2A + 2B - 1
-3
it is 3/6, which when simplified is 1/2
2/3 minus 1/6 is the same as 4/6 minus 1/6 = 3/6 or 1/2 simplified
minus 6
well... order of operations... says 7 + (2x3) - (5x2) which is 7 + 6 - 10 simplified as 13 - 10
