Solve for x. ax + by = −c
x equals the quantity negative b times y minus c all over a
x equals the quantity negative b times y plus c all over a
x equals the quantity b times y plus c all over a
x equals the quantity b times y minus c all over a

Your answer is the first option, x equals negative B times y minus C all over A.

To answer this it would be helpful to rearrange the equation to get it in the form “x =“:
Ax + By = -C
Ax = -C - By
x = (-C - By)/A
which we can also write as
x = (-By - C)/A

So now that we know what x equals we just have to write it in word form. We can see that both B and C are negative, which rules out all of the options except for the first one.
This is because in the second option, it says “plus C”, which implies C is positive.
In the third option, it says “the quantity B” instead of “the quantity negative B”, which implies that B is positive. This is also true for the last option.

This means that the first statement is the only one that could be true, so that’s the answer.
I hope this helps!
