Answer 2

Given:

• The sum of two numbers is 45.
• One number is nine more than thrice the other number.

To find:

• The numbers?

Solution:

• Let's consider the two numbers as x & 3x + 9.

Here,

• The sum of these two numbers is 45.

• Lets take x in common.

⠀⠀━━━━━━━━━━━━━━━━━━━⠀

« Now, Forming an equation,

→ x + (3x + 9) = 45

→ 4x + 9 = 45

→ 4x = 45 - 9

→ 4x = 36

→ x = 36/4

→ x = 9

Therefore,

• The numbers are:

1. 9
2. 3x + 9 = 3(9) + 9 = 27 + 9 = 36

∴ Hence, The two numbers are 9 & 36.

⠀⠀━━━━━━━━━━━━━━━━━━━⠀

« Now, Let's verify this,

→ x + (3x + 9) = 45

→ 9 + (3(9) + 9) = 45

→ 9 + (27 + 9) = 45

→ 9 + 36 = 45

→ 45 = 45

LHS = RHS

• Hence, Verified!
