7^6 is the correct answer
No matter where the negative sign is, the product will always be negative, so is the number itself.
13.2(-8.1)=-106.92
twice of that would be -213.84.
first do the multiplying, then the adding(the adding of negative numbers, so it would be basically subtracting).
6( x - 4) = 7
6 x - 24 = 7
6 x = 7 + 24
6 x = 31
x = 31/6
6 ( 31/6 - 4) = 7
186/6 - 24 = 7
186/6 = 144/6 = 7
42/6 = 7
7 = 7
