Answer:
Option C.
Step-by-step explanation:
The given equations are


We need isolate one of the variables, such that it appears by itself on one side of the equation.
Isolating a variable in two equations is easiest when one of them has a coefficient 1.
In equation 1, coefficient of B is 1. So, we can easily isolate one of the variables.
The equation is

Subtract 3A from both sides.

Multiply both sides by -1.

Therefore, the correct option is C.

Answer:
There are 525 calories in a banana split.
Step-by-step explanation:
We know that a banana has 80 calories and 5 calories less than this
80 - 5 = 75 calories

This means that the banana split will have 7 times 75 calories
75 * 7 = 525
There are 525 calories in a banana split.
