Answer 2

Answer:

=> y = 4

Step-by-step explanation:

Given that:-

$3-2(2-y)=7$

To find:- The value of the expression,

In order to solve that, we have to use the concept of BODMAS:

It is the sequence of various mathematical operations which is used to solve the various expressions.  

As we know,

=> $3-2(2-y)=7$

Now, rearrange the terms:

=> $3-2(-y+2)=7$

Distributing the terms,

=> $3-(-2y+4)=7$

=> $3+2y+4=7$

Subtract the numbers,

=> $-1+2y=7$

Rearrange the terms,

=> $2y-1=7$

Add $1$ on both sides, we get

=> $2y=8$

Divide by $2$ on both sides,

=> $y=4$

Hence, the required solution is 4.
