Hey there! I'm happy to help!
We have two values for y. Since y=y, this means that −2x + 4 and − 1/3x − 1 are equal as well, so we can put them in an equation and solve for x.
−2x + 4 = − 1/3x − 1
We subtract 4 from both sides.
-2x=-1/3x-5
We add 1/3 x to both sides.
-5/3x=-5
We divide both sides by -1 2/3.
x=3
Now, we plug this into one of the original equations to find y.
y=-2(3)+4
y=-6+4
y=-2
Therefore, the solution is (3,-2) or x=3 and y=-2.
I hope that this helps! Have a wonderful day! :D

The probability that the first student is a girl is 5/10.
The probability of the second selection being a boy is 5/9.
(since the first selection was a girl, there are 9 students left)
The probability that the third student is a girl is 4/8
(there are 4 girls left after one was selected, and 8 students left in total, after the second selection.
The probability is (5/10)(5/9)(4/8)=0.139
Answer: 0.139
I hope this helps you
