Answer 1

Solution

Given equation

→ 13×( y - 4 ) - 3( y - 9 ) = 5 ( y + 4)

Now solve the equation  

→ 13×( y - 4 ) - 3( y - 9 ) = 5 ( y + 4)

→ 13y - 52 - 3y + 27 = 5y + 20

→ 10y - 25 = 5y + 20

→ 10y - 5y = 20 + 25

→ 5y = 45

→y = 45/5

→y = 9

Answer :- y = 9

Now check our equation

→ 13×( y - 4 ) - 3( y - 9 ) = 5 ( y + 4)

Where y = 9

→ 13×( 9 - 4 ) - 3( 9 - 9 ) = 5 ( 9 + 4)

→ 13 × 5 = 5 × 13

→ 13/13=5/5

→1 = 1

LHS = RHS
