Question

If four times a number is decreased by five,the result is thirty-one in mathematical language

Answer 1

Answer:

9

Step-by-step explanation:

Let the number be x

According to the question

4 times a number decreased by 5 = 31

∴ 4x - 5 = 31

4x = 31 + 5

4x = 36

On dividing both sides by 4, we get

x = 9

Hence, the number is 9
