Part A: 3x + 15 = 5x - 25
Part B: x = 20
This is false... you can get an easy example: (-2) + (10) = 10 - 2 = 8
60-41 1/2=18 1/2 18 1/2 divided by 1/2=37/2*2 (cross cancel 2s)=37
The way to work this out is to find a common denominator. so in this case 80 is a common denominator. So it would be 3/8 into 30/80 and then 4/10 into 32/80 therefore 4/10 is bigger
