Hola, me gustaría que me indicarais cómo resolver la siguiente ecuación logarítmica: logx^2-3logy=7 logx+logy=1 Muchas gracias

logx²-3logy=7
logx+logy=1
x>0 y>0
logx²-logy³=7
logxy=1
log(x²/y³)=log10
logxy=log10
x²/y³=10
xy=10
x²/y³=10
x=10/y
(10/y)²/y³=10
(10²/y²)/y³=10
10²/y=10
y=10²/10
y=10
y=(1/10)
y=1/10
x=10/(1/10)
x=10*10
x=100
