Answer:
11.8845
Step-by-step explanation:
11.8845 to the up and down answer it will be down
53y-42y=55
11y=55
Y=55/11 =5
X-4y=-18
an easy way is to solve for oone variable
solve for x
add 4y both sides
x=4y-18
when y=1, x=-16
when y=0, x=-18
when y=2, x=-10
(x,y)
so some orderd pairs are
(-16,1)
(-18,0)
(-10,2)
