Hi,

   |Multiplying thru by 12 so as all denominators = 1

   8y - 9 = 5 

Answer by checkley79(3341)   (Show Source): You can put this solution on YOUR website!
 (2y)/(3)-(3)/(4)=(5)/(12) FIND THE LOWEST COMMON DENOMINATOR.(12)

[4*2Y-3*3]/12=5/12

[8Y-9]/12=5/12 CANCEL THE LIKE DENOMINATORS.

8Y-9=5

8Y=5+9

8Y=14

Y=14/8

Y=7/4 ANS.

PROOF:

(2*7/4)/3-(3)/(4)=(5)/(12)

(14/4)/3-3/4=5/12 INVERT THE (/3) & MULTIPLY.

14/4*1/3-3/4=5/12

14/12-3/4=5/12 CHANGE 3/4 TO 9/12

14/12-9/12=5/12

5/12=5/12
