Question

y/3+2=2y+15/4 WHO to SOLVE
​

Answer 1

Answer:

-21/20

Step-by-step explanation:

y/3+2=2y+15/4

y+6/3=8y+15/4

Cross multiply 4y+24=24y+45

20y=-21

Hence y=-21/20

Answer 2

Answer:

• If y/3 + 2 = 2y + 15/4 then y = -3/10

• If y/3 + 2 = (2y + 15)/4 then y = -7

Solution:

We have ;

=> y/3 + 2 = 2y + 15/4

=> (y + 6)/3 = (8y + 15)/4

On cross-multiplication , we get ;

=> 4•(y + 6) = 3•(8y + 15)

=> 4y + 24 = 24y = 30

=> 4y - 24y = 30 - 24

=> - 20y = 6

=> y = 6/(-20)

=> y = -3/10

Hence,

The required value of y is –3/10 .

Another probable question:

=> y/3 + 2 = (2y + 15)/4

=> (y + 6)/3 = (2y + 15)/4

On cross-multiplication , we get ;

=> 4(y + 6) = 3(2y + 15)

=> 4y + 24 = 6y + 45

=> 4y - 6y = 45 - 24

=> - 3y = 21

=> y = 21/-3

=> y = -7

Hence,

Required value of y is (–7) .
