Question

Solve the following equation using cross multiplication method
1/2(y+1)+1/12+1/14(y-1/3)=y/2
​

Answer 1

Answer:

This equation  can't be solved  using cross multiplication method because the method is using only for 3 variables. There is one variable.

Step-by-step explanation:

1/2(y+1)+1/12+1/14(y-1/3)=y/2

or, y+1 + 1/6 + 1/21(y-1) = y            [ eliminating 1/2 from both side ]

or, 1 + 1/6 + y/21 - 1/21 = 0            [ as, y-y = 0 ]

or, 7/6 + y/21 - 1/21 = 0

or, y/21 = - 47/42

or, y = - 47/2

So, the answer is:  y = - 47/2
