Question

Помогите решить срочно

Answer 1

Ответ:

$\\ \left \{ {{x-y = 1} \atop {4^{2x-3y} = 1}} \right.$

$\{{{x=1+y} \atop {4^{2x-3y}=1 }} \right.$

$4^{2(1+y)-3y} =1$

$y=2$

$x=1+2$

$x=3$

$(x,y) = (3,2)$

$\left \{ {{3-2=1} \atop {4^{2*3-3*2} }=1} \right.$

$\left \{ {{1=1} \atop {1=1}} \right.$

$(x,y) = (3,2)$
