Question

q.5 22 subtracted from thrice a number is 68. Find the number​

Answer 1

Answer :-

• The required number is 30.

Given :-

• 22 subtracted from thrice a number is 68.

To find :-

• The number.

Step-by-step explanation :-

• Let the number be "x".

• Thrice the number = 3x.

• 22 subtracted from thrice the number = 3x - 22.

• Now, it has been given that the result is 68.

----------------------------

Hence,

$\longmapsto\sf3x - 22 = 68$

Transposing 22 from LHS to RHS, changing it's sign,

$\longmapsto\sf3x = 68 + 22$

Adding 22 to 68,

$\longmapsto\sf3x = 90$

Transposing 3 from LHS to RHS, changing it's sign,

$\longmapsto\sf x = \dfrac{90}{3}$

Dividing 90 by 3,

$\longmapsto\overline{\boxed{\sf x = 30}}$

----------------------------

• Hence, the number is 30.

Answer 2

Step-by-step explanation:

number=y

Thrice of a number=3y

22 is subtracted= 3y-22=68

3y=68+22

3y=90

y=90/3=3
