Answer:
x = 27/4
Step-by-step explanation:
3x + 2y = 12 and 5x – 2y = 42
Add the two equations together to eliminate y
3x + 2y = 12
5x – 2y = 42
-----------------------
8x = 54
Divide each side by 8
8x /8 = 54/8
x = 27/4
Work out 8% of 30000
10% of 30000 is 3000
1% of 30000 is 300
2% of 30000 is 300x2=600
Therefore 10%-2%= 3000-600=2400
It therefore follows that Mayra earned 4540 + 2400 = 6940 for January
