Answer 2

Question:

If 7 is added to five times a number, the result is 57. Find the number.

Answer:

number = 10

Step-by-step explanation:

Let's say the number is x.

Given that if 7 is added to five times a number. Means (5x + 7) then it's result is 57.

From above we can write like

→ 5x + 7 = 57

Substitute -7 on both sides,

→ 5x + 7 - 7 = 57 - 7

→ 5x = 57 - 7

→ 5x = 50

Divide by 5 on both sides,

→ 5x/5 = 50/5

→ x = 10

Hence, the required number is 10.

Verification:

Substitute value of x = 10 in 5x + 7 = 57

5(10) + 7 = 57

50 + 7 = 57

57 = 57

Hence, proved.
