Answer:
When doing short equations like this, you want to use P.E.M.D.A.S. That just means you want to use <u>parentheses first, exponents second, multiply third, divide fourth, add fifth, and subtract last</u>. In this case, since there are no parentheses, or subtraction, or exponents, we cross those three out, and make multiplication our top priority. But, what exactly does <em>seven p </em>mean? <em>p</em> is an assigned, substituted number. Sometimes people will use <em>p</em> instead of <em>x</em> as subs, but it really does not matter. So now that we have enough information, let's start.
The next step is to divide <em>q</em>(12) by three. Before adding, you want to divide, because it is your second-top-priority.
Lastly, add the quotient and the product together.
And we are done! The result is 46, so that means your answer is D! Yay!

Answer:
The lines representing these equations intercept at the point (-4,2) on the plane.
Step-by-step explanation:
When we want to find were both lines intercept, we are trying to find a pair of values (x,y) that belongs to both equations, which means that it satisfies both equations at the same time.
Therefore, we can use the second equation that gives us the value of y in terms of x, to substitute for y in the first equation. Then we end up with an equation with a unique unknown, for which we can solve:
Next we use this value we obtained for x (-4) in the same equation we use for substitution in order to find which y value corresponds to this:
Then we have the pair (x,y) that satisfies both equations (-4,2), which is therefore the point on the plane where both lines intercept.
