So if y=-5x-23 then we can plug that value in for y in x-10y=6, so it becomes
x-10(-5x-23)=6
x+50x+230=6
51x=-224
x=-4.39
plug this x value into the equation y=-5x-23
y=-5(-4.39)-23
y=21.95-23
y=-1.05
Answer:8
Step-by-step explanation:
You find the average which is adding them all together then dividing by how many numbers you added.
