I believe the variable d equals 13. Since the rule is x-6=y. So you just incorporate 7, since 7=y the equation now will look like x-6=7. Now you just solve it. X=13 other known as d=13.
Solving for variables is easy as all we must do is isolate the variable and simplify. In this case, to isolate the variable, we simply need to divide "n" by 10 (because the "n" is being multiplied by 10).
10n=40
/10 /10
n=4
Using the math above, we can see that n=4.
