Question

four times a number reduced by 5 equals 19 find the number​

Answer 1

Answer:

6

Step-by-step explanation:

let the no. be x

then 4 times of x =4x

reduced by 5=4x-5=19

now,

4x=19+5 (by transposition)

4x=24

x = 24/4 = 6

hence the no. is 6

Answer 2

Answer:

The required number is 6.

Step-by-step-explanation:

Let the number be x.

Now,

Four times the number = 4x

From the given condition,

4x - 5 = 19

⇒ 4x = 19 + 5

⇒ 4x = 24

⇒ x = 24 ÷ 4

⇒ x = 6

∴ The required number is 6.

─────────────────────────

Verification:

By substituting x = 6 in the LHS of the equation we have,

4x - 5 = 19

LHS = 4x - 5

⇒ LHS = 4 * 6 - 5

⇒ LHS = 24 - 5

⇒ LHS = 19

RHS = 19

∴ LHS = RHS

Hence verified!
