Question

If 8 is added to 4 times a number, the result is two less than 5 times the number. Find the number​

Answer 1

Step-by-step explanation:

Let the number be x

Four times a number = 4x

8 added to 4 times a number = 4x + 8

The result is 2 less than 5 times the number =5x-2

The number is 10.

According to the question,

4x + 8 = 5x - 2

➾ 4x - 5x = -2 - 8

➾ -x = -10

By cancelling the minus (-) sign

➾ x = 10

Verification :-

4x + 8 = 5x - 2

➾ 4x - 5x = -2 - 8

➾ -x = -10

➾ x = 10

By putting the value of x

➾ 10 = 10

∴ LHS = RHS
