Four is subtracted from four times some number and the result is the sum of the number and five

Question

I do not know how to make into an equayon

Answer 1

let n = the number

Four subtracted from 4 times the number means 4n - 4

The sum of the number and 5 is n + 5

These two expressions must be the same, i.e. the result of the original multiplication and subtraction is n + 5

 

Therefore,

4n - 4 = n + 5

Add 4 to each side

4n = n + 9

Subtract n from each side

3n = 9

Divide by 3

n = 3

Now go back and make sure the answer satisfies he condition of the problem.
