Q4. Solve the given equation and check your result .
4(2b + 1) = 36

Answer 1

Step-by-step explanation:

8b+4=36

8b=36-4

8b=32

b =4

check

4(2b+1)=36

4(2(4)+1)

4*9

36

L.H.S.= R.H.S

hence proof

Answer 2

Answer:

$4(2b + 1) = 36 \\ 8b + 4 = 36 \\ 8b = 32 \\ b = 4$

Verification

LHS

4(2b + 1)

= 4[2 × 4 + 1]

= 4[8 + 1]

= 4 × 9

= 36

RHS
