Answer: <em>Hey, It's me, Lily!!</em>
Step-by-step explanation:
1) x = −5/2
2) x = 4
3) x = 5
4) x = 6
5) x = 7
<u>Hope This Helps!! (^ '--')</u>
X = pencils, y = pens
8x + 6y = 8.50
4x + 4y = 5.....multiply by -2
----------------
8x + 6y = 8.50
-8x - 8y = -10 (result of multiplying by -2)
-----------------add
-2y = - 1.50
y = -1.50 / -2
y = 0.75 <=== pens cost 0.75
4x + 4y = 5
4x + 4(0.75) = 5
4x + 3 = 5
4x = 5 - 3
4x = 2
x = 2/4
x = 0.50 <== pencils cost 0.50
Point two should be your answer
