Answer:
x = -7, y = -9
Step-by-step explanation:
The coefficient (the number before) the y is the same but the signs are opposite so add the equations together:
x-3x+y-y=-16+30
-2x=14
x=-7
y=-16-x=-16--7=-9
The.value of x woukd be 2
12*a^3 -6a^2 + 27a + 8a^2 -4*a +18 =
12*a^3 +2*a^2+23*a +18
What is the complete question and what are the choices??
The correct answer is 9p if you were to simplify
