The answers to the questions
2x + y = -3
x - 2y = -4
2x + y = -3
2x - 4y = -8
----------------
5y = 5
y= 1
2x + y = -3
2x + (1) = -3
2x = -4
x = -2
Solution: x = -2, y = 1

Answer:
0.4x < 0.5x
Step-by-step explanation:
Let x = Amount of money Rosa and Albert earn each week
Rosa:
Rosa spends 0.4(x) and 2/5(x) each week on video games and pizza
That equals to :
Rosa spends 0.8x, or 80% of her allowance on video games and pizza
Albert
Albert spends 1/2(x) and 0.25(x) each week on video games and pizza
Albert spends 0.75x, or 75% of her allowance on video games
Rosa spends 0.4x on video games, and Albert spends 0.5x.
0.4x ≤ 0.5x
