The system of equations is
x - 2y = 2          (1)
3x + y = 6         (2)

From (1), obtain
x = 2y + 2        (3)

Substitute (3) into (2).
3(2y + 2) + y = 6
6y + 6 + y = 6
7y = 0
y = 0
From (3), obtain
x = 2*0 + 2 = 2

Answer:  (2, 0)  or x=2, y=0

balu736 [363]

Atticus will spend $1.60 on wrapping paper.

Step-by-step explanation:

Given,

Cost of paper per yard = $2.40

Atticus wants to buy = 2/3

Cost of 2/3 yards of paper = \frac{2}{3}*2.40

Cost of 2/3 yards of paper = \frac{4.80}{3}

Cost of 2/3 yards of paper = $1.60

Atticus will spend $1.60 on wrapping paper.
