2x - 3y = -12 ⇒ 2x - 3y = -12⇒ 2x - 3y = -12
x + y = 1 ⇒ 2(x + y) = <u>1⇒ 2x + 2y = 1</u>
y = -11
2x - 3y = -12
2x - 3(-11) = -12
2x + 33 = -12
<u> - 33 - 33</u>
2x = -45
<u> 2x</u> = <u>-45</u>
2 2
x = -22.5
(x, y) = (-22.5 , -11)
Since each pound casts $0.58 and the total spent is $2.03, you divide 2.03 by .58 to find the total amount of pounds.
2.03/.58=203/58=3.5
