Step-by-step explanation:

u newd to take constants on one side and just calculate the answer

Answer 2

Solution:

Given,

→ 3a + 21 = 45

Moving 21 to right side, we get,

→ 3a = 45 - 21

→ 3a = 24

Dividing both sides by 3, we get,

→ 3a/3 = 24/3

→ a = 8

Ф So, the value of a is 8.

Verification:

Let us verify our result. To verify our result, we have to check whether Left Hand Side is equal to the Right Hand Side.

Putting a = 8, we get,

→ LHS = 3 × 8 + 21

→ LHS = 24 + 21

→ LHS = 45

→ LHS = RHS, Hence Verified.

Ф So, our answer is correct.

Answer:

• a = 8
