Seven less than four times a number is 35 What is the number

Seven less than four times a number is 35. What is the number?

Solution

Let the number be x. Then from the given information we can frame a linear equation which is

7- 4x = 35

subtract 7 both sides we get

-4x = 35-7

=> -4x = 28

Now divide both sides by -4 , we get

x = 28/-4 = -7

Hence the number is -7
