Question

Which equations show you how to find 16 - 9

Answer 1

9+x=16
Subtract9 from both sides
X=7

Answer 2

There is an infinite number of equations that match the substraction 16-9

Explanation:

First of all, we are asked to find an equation whose fina result is 16-9. Since we do not have any other restriction or limit to take on account with, we can simply write any equation we like as long as the value of the unknown variable. So, for example, we can choose the equation
`9+x=16` or maybe
`18+2x=32`, or
`42x+9=16+41x`.

As you can see, there is an infinite number of combining numbers and variables to form an equation whose final value is 16-9.
