If (p, q) is the solution to the system of equations, what is the value of q? −16p − 2q = 100
p − 4q = 200

The solution to the system of equations

Hence, the value of q = -50

Step-by-step explanation:

Given the system of equations

solving to determine the value of q

Multiply p − 4q = 200 by 16:      

so adding the equations

so

solve -66q = 3300

Divide both sides by -66

substituting q = -50 in −16p − 2q = 100

Subtract 100 from both sides

Simplify

Divide both sides by -16

Thus, the solution to the system of equations

Hence, the value of q = -50

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
