Question

Solve the equation 9y- 4= 3( y + 1) + 8 and check your answer.​

Answer 1

Answer:

( 9y - 4 ) = 3 ( y + 1 ) + 8

9y - 4 = 3y + 3 + 8

9y - 4 = 3y + 11

9y - 3y = 11 + 4

6y = 15

y = 15/6

y= 5/2

Answer 2

Answer:

9y - 4 = 3(y + 1) + 8

9y - 4 = 3y + 3 + 8

9y - 3y = 3 + 8 + 4

6y = 15

y = 15/6 = 5/2

y = 5/2

Step-by-step explanation:

9× 5/2 - 4/1 = 3(5/2 + 1/1) + 8

45/2 - 4/1 = 3 × 7/2 + 8

(45 - 8) = 21/2 +8/1

37 = (21 + 16)

37 = 37

Hence y = 5/2
