Step-by-step explanation:
2x/3 + 3y/5 = 17 3x/4 + 2y/3 = 19
(10x + 9y)/15 = 17 (9x + 8y)/12 = 19
10x + 9y = 255 9x + 8y = 228
[10x + 9y = 255] × 8 [9x + 8y = 228] × 9
80x + 72y = 2040 81x + 72y = 2052
⬆️ SUBTRACT ⬆️
x = 12
Now
2*12/3 + 3y/5 = 17
24/3 + 3y/5 = 17
8 + 3y/5 = 17
3y/5 = 9
3y = 45
y = 15
