Answer:
Let's solve by eliminating x. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.
18x−21y=24
−18x+10y=−2
Add the two equations.
−11y=22
Divide by -11 to isolate y.
y=−2
Substitute y=−2 into either of the 2 equations, I'll just use the second one.
9x+10=1
9x=−9
x=−1

Answer: 0.790
Step-by-step explanation:
Given : The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level.
The sample size : n= 2004
The number of students read above the eighth grade level = 1584
Then , the proportion of students read above the eighth grade level is given by :-

Hence, the estimate proportion of tenth graders reading at or below the eighth grade level =0.790
