ответ: x = 4; y = 5.
Объяснение: 2x + y = 3
3x + 2y = 2
1. 2x + y = 3
y = 3 - 2x
2. 3x + 2y = 2
3x + 2(3 -2x) = 2
3x + 6 - 4x = 2
-x = -4
x = 4
3. При x = 4 2x + y = 3
2×4 + y = 3
8 + y = 3
y = 8 - 3
y = 5
ответ: x = 4; y = 5.
Объяснение: 2x + y = 3
3x + 2y = 2
1. 2x + y = 3

2. 3x + 2y = 2
3x + 2(3 -2x) = 2
3x + 6 - 4x = 2
-x = -4
x = 4
3. При x = 4 2x + y = 3
2×4 + y = 3
8 + y = 3
