Answer 1

Hi Darian;
[(1/4)(13y-3)]+[(1/8)(6y+9)]
[(13y/4)-(3/4)]+[(6y/8)+(9/8)]
Multiply first bracketed equation by 2/2 such that both bracketed equations have 8 as a denominator...

{(2/2)[(13y/4)-(3/4)]}+[(6y/8)+(9/8)]

[(26y/8)-(6/8)]+[(6y/8)+(9/8)]

Combine like terms...

(32y/8)+(3/8)

4y+(3/8)
