Question 1 Linear Equations in one variable Exercise 7B

Thrice a number when increased by 5 gives 44. Find the number.

Answer:

Solution:-

Let the required number be x.

Then,

= 3x + 5 = 44

Transposing 5 to RHS and it becomes -5.

= 3x = 44 - 5

= 3x = 39

Multiplying both side by (1/3)

= 3x × (1/3) = 39 × (1/3)

= x = 13

∴ the required number is 13
