144, 4:6 simplifies to 2:3, if you divide 96 by 2 you get 48, and 48 x 3 = 144
10x -15y=45
9x+15y= 12
19x= 57
x= 3
3(3)+5y= 4
9 + 5y = 4
5y = -5
y = -1
(3,-1)
Find the GCF of both numerator and denominator and then divide both the denominator and numerator by that and you will get the simplified fraction.
Replace x with and simplify
