Question

Give answer of the following

Solve by BODMAS method and verify --

1. 5a+4=39

Answer 1

Answer:

a = 7

Step-by-step explanation:

5a + 4 = 39

⇒ 5a = 39 - 4

⇒ 5a = 35

⇒ a = 35 / 5

⇒ a = 7

Verification:

Putting the value of a in 5a + 4 = 39,

5a + 4 = 39

⇒ 5 * 7 + 4 = 39

⇒ 35 + 4 = 39

⇒ 39 = 39

LHS = RHS

Hence, the value of a is 7.
