Question

find a number which when multiplied by 7 is increased by 78

Answer 1

Answer:

let the number be X.

therefore, (X×7)-(X) =78.

so, 7X-X=78.

So,6X=78.

X=13.

Answer 2

Step-by-step explanation:

let the number be x

x * 7 = x + 78

7x = x + 78

7x - x = 78

6x = 78

x = 78 / 6

x = 13

ans is 13
