Respuesta:
x = 5 ; y = 2
Explicación paso a paso:
4x + 5y = 30 / *1
3x - 5y = 5 / * 1
valor x
4x + 5y = 30
3x - 5y = 5
4x = 30
3x = 5
7x = 35
x = 35/ 7
x = 5
valor y
3 * 5 - 5y = 5
15 - 5y = 5
-5y = 5 - 15
-5y = -10
y = -10/-5
y = 2
comprobación
4 * 5 + 5 * 2 = 30
20 + 10 = 30
30 = 30 ✅✅
3 * 5 - 5 * 2 = 5
15 - 10 = 5
5 = 5 ✅✅
espero te sirva :) <3
