I can't really tell if the question is asking about 7 or -7, so I'll give the answer for both.
A multiplicative inverse for 7 is a number you can multiply by 7 to make it equal to 1. In terms of an equation, you would get 7x = 1. We can then solve for x by dividing both sides by 7. So x = 1/7.
For -7, you would be able to solve the same equation as above just with -7 in the place of 7. You would end up with x = -1/7.
Substitute in the values for y and x into the equation.
so..
8 - 4.7(-1) - (2) solve the equation
8 + 4.7 -2
12.7 - 2
10.7
