Answer:
y + 0.5 = 3(x - 2)
y + 0.5 = 3x - 6
y = 3x - 6.5
Step-by-step explanation:
I don’t know there’s no picture B?
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
you would divide both sides by 6 to get your answer. i hope this helps :)
