⇒ 7( y - 2 ) - 4 ( 5 + y ) = 10
⇒ 7y - 14 - 20 - 4y = 10
⇒ 3y - 34 =10
⇒ 3y = 44
⇒ y = 44 /3.
Verification : 7 { ( 44/3) - 2 } - 4 { 5 + (44/3) }
7( 44 - 6 ) 4 ( 15 + 44 )
= ---------------- - ---------------------
3 3
7 ( 38 ) - 4 ( 59 )
= ----------------------------------

= 30/3 = 10 verified.
So, y = 44/3.
⇒ 7y - 14 - 20 - 4y = 10
⇒ 3y - 34 =10
⇒ 3y = 44
⇒ y = 44 /3.
Verification : 7 { ( 44/3) - 2 } - 4 { 5 + (44/3) }
7( 44 - 6 ) 4 ( 15 + 44 )

So, y = 44/3.
