Question

Solve the following equatirus and check the answers :
(a) 3(y+1) – 2(y+1)=5
​

Answer 1

Answer:

y = 7

Step-by-step explanation:

3(y+1) - 2(y+1) = 5

3y + 1 -2y -3= 5

y - 2 = 5

y = 5 + 2

y = 7

Answer 2

Answer:

= 3y + 3 - 2y + 2 = 5

= 3y - 2y + 3 - 2 = 5

= 1y + 1 = 5

= 1y = 5 - 1

= 1y = 4

= y = 4/1

= y = 4

Check:-

= 3(4+1) - 2(4+1) =5

= 3*5 - 2*5 = 5

= 15 - 10 = 5

= 5 = 5

Hence prooved.

LHS = RHS.

Hope it helps.
