Question

Mama had several notebooks. If she give 13 notebooks to each of her children, she will have 8 left. If she give 15 notebooks to each of her children, she will have nothing left. What is the smallest number of notebooks and children does mama have?

PLEASE HELP QUICKLY!!

Answer 1

Children=4

Notebooks=60

It said mama's got an amount of books, so you can transform this into a equation

X=children

Notebooks= 13x +8

Notebooks= 15x

Now you just establish a system of equations, thus notebooks=notebooks

13x + 8= 15x

2x=8

X= 4
