210 / 0.42 = 500

500 people were surveyed.

Which ordered pair satisfies the system of equations shown below? (10 POINTS + BRAINLIEST ANSWER)

nasty-shy [4]

The answer would be D.
you would start by choosing one of the variables to eliminate, i chose to eliminate X first. in order to eliminate X, i had to multiply the second equation by -2. X then cancelled out, and i solved for the Y the same way you would a 1 step equation. Y=-4
I then took the first original equations, plugged Y in, and solved for X. X=3.

Hope this helps!
