Answer:
The answers B and C are true statements
Step-by-step explanation:
To find if this works for each equation, input the -3 in for x and the 1 in for y. If the statement is true, then it works.
x - 4y = 6
(-3) - 4(1) = 6
-3 - 4 = 6
-7 = 6 (FALSE)
Therefore it does not work for the first equation.
3x + y = -8
3(-3) + (1) = -8
-9 + 1 = -8
-8 = -8 (TRUE)
Therefore it works for this equation.
