Respuesta :

Let M be the number of magazines Justin would have left to read after reading R of them, then we can set the following equation:

[tex]M+R=16.[/tex]

If R=9, then:

[tex]M+9=16.[/tex]

Solving the above equation for M we get:

[tex]M=16-9=7.[/tex]

Answer: After reading 9 magazines, Justin has 7 left to read.
