Question

2x + 4y = 8

X+ 2y = 4
Which of the following statements about the ordered pair (-2, 3) is TRUE?
A. It is a solution to the first equation but not the second equation.
B. It is the only solution to the system of equations.
C. It is one of many solutions to the system.
D. It is not a solution to either equation.

Answer 1

C

Explanation:

First we distribute (-2,3) into the equations so 2x+4y becomes 2(-2)+4(3) so that's -4+12 which is 8 making equation 1 correct.

Then x+2y becomes (-2)+2(3) which is 4 so the second equation is correct as well therefore the answer has to be C because of process of elimination
