Question

$1 left { {{4^{log4(2x)}-y=-1 } atop {5^{2x-y}+ 5^{x}=5,2 }} right. 2 left { {{ 3^{log3(y+x)}=2 } atop {2^{2x+y}=16 }} right.$Решите систему уравнений! Математика!10 класс!

Answer 1

1)2x-y+1=0--->y=2x+1
   5+5^x=5.2--->5^x=0.2---->x=log5(0.2);y=2log5(0.2)+1
2)y=2-x
2^(x+2)=2^4--->x=2; y=0
