Answer:
The solutions to the system of equations are:

Thus, option C is true because the point satisfies BOTH equations.
Step-by-step explanation:
Given the system of the equations

Arrange equation variables for elimination






solve for x

Divide both sides by -2






The solutions to the system of equations are:

Thus, option C is true because the point satisfies BOTH equations.
So we are trying to find the numerator of 42 in relation of 6/7.
42 divided by 7= 6 So 6 x 6 from the numerator of 6/7 = 36.
So 6/7 written as a fraction with a denominator of 42 is 36/42.
