Answer:
C.
Step-by-step explanation:
Because there is constant term 4 in the question, but there is no any such constant term in the given options.
Answer:
X=-1, y=1
Step-by-step explanation:
Substitute value of y in first equation (3x+4) with y of second equation.
2x-4(3x+4)=-6
2x-12x-16=-6
-10x=10x=-1
solve for y but putting -1 for x value in either equation
y=3(-1)+4
y=-3+4
y=1
