So it would be 6 times a number n and then subtracting 7 = -49
therefore you have the equation
6(n)-7=-49
or
6n-7=-49
if you want to solve for n, you need to add 7 on both sides of the equation
6n-7=-49
+7 +7
therefore you have 6n=-42
and dividing by 6 on both sides gives you n=-7.
so the answer is n=-7
