AB + BC = AC
3y - 1 + 7y = 29
10y - 1 = 29
10y = 29 + 1 = 30
y = 30/10 = 3

AB = 3(3) - 1 = 9 - 1 = 8

How do you simplify a fraction?

attashe74 [19]

You simplify a fraction by finding it's greatest common factor. A greatest common factor is what both numbers are divisible by. If they can both be divided by two, then you've simplified them a little bit. Keep going until you can't find a common number that can be divided by the two, and you've got your simplified fraction. For example, 10/5 = 1/2 since both 10 and 5 is divisible by 5.
