Answer:
x=-4 y=5
Step-by-step explanation:
Rewrite equations:
x=−4y+16;3x+4y=8
Step: Solvex=−4y+16for x:
x=−4y+16
Step: Substitute−4y+16forxin3x+4y=8:
3x+4y=8
3(−4y+16)+4y=8
−8y+48=8(Simplify both sides of the equation)
−8y+48+−48=8+−48(Add -48 to both sides)
−8y=−40
−8y
−8
=
−40
−8
(Divide both sides by -8)
y=5
Step: Substitute5foryinx=−4y+16:
x=−4y+16
x=(−4)(5)+16
x=−4(Simplify both sides of the equation)
Answer:
x=−4 and y=5

Juan is in the middle
<u>Explanation:</u>
Given:
Five students in total
_ _ _ _ _
Juan is not the shortest. So, Juan can be in 2nd, 3rd, 4th or 5th position.
_ J J J J
Tad is the tallest and not standing next to Juan, So,
_ J J _ T
Caroline is next to Tad. So,
_ J J C T
Juan is not standing next to Pamela. So,
P _ J C T
Marco is taller than Pamela. So,
P M J C T
The height is arranged in increasing order from Pamela to Tad.
Thus, from the series we can see that Juan is in the middle.
