Question

a number which is multiplied by and then added by 5 is equal to 10 the equation representing this is​

Answer 1

Answer:

In short, the answer is 35

To answer this we are allowed to suppose that the missing number is X. This will help us solve it.

The student first added 10 to the number and theb multiplied with 5. He got 75. So, what he really did was the following:

(X+10) and then multiplied: (X+10)*5 = 75 <=>

5*X + 5*10 = 75 <=> 5*X = 75 - 50 <=> 5*X = 25 <=> X=5

In case he did what he was supposed to do he would have gotten the following result

5*5 = 25

25+10 = 35
