Answer:
x = 1, y = 1
Step-by-step explanation:
3x - 4y = -1
5x + 2y = 7
If we multiply the whole second equation by 2, we get:
10x + 4y = 14
Adding this to the first equation:
10x + 4y + 3x - 4y = 14 - 1
13x = 13
x = 1
Applying this to the second equation:
5 (1) + 2y = 7
2y = 2
y = 1

<h2>$40,000</h2>
Step-by-step explanation:
Andrew paid 30% in taxes, which means he has 70% remaining

C = $28,000 / 70% = 28000/0.7 = $40,000
