Given

If 10 is added to four times a certain number, the result is 5 less than five times the number.

To Find

The number.

Solution

Let number be 'x'.

It is given that 10 is added to four times the number.

4x + 10

Then

result is 5 less than five times the number

5x - 5

It means both equations are equal.

4x + 10 = 5x - 5

Subtract 'x' from both sides,

4x + 10 - 4x = 5x - 5 - 4x

10 = x - 5

Now,

Add 5 to both sides,

10 + 5 = x - 5 + 5

15 = x

Answer

So, the certain number which satisfies the given statements is 15.

Verification

Solving LHS,

4x + 10

4 × 15 + 10

60 + 10

70

Solving RHS,

5x - 5

5 × 15 - 5

75 - 5

70

LHS = RHS

Hence, verified.
