Question

1260:(x·y-2)=35 determinati nr.de solutii pentru x si y

Answer 1

Salut,

1260:(x•y-2) = 35
xy-2 = 1260:35
xy-2 = 36
xy = 38.

{ x1 = 19
{ y1 = 2.

{ x2 = 2
{ y2 = 19.

{ x3 = 1
{ y3 = 38.

{ x4 = 38
{ y4 = 1.

Succes!

Answer 2

1260 impartit la (x*y-2)=35
(X*Y-2)=a
1260 impartit la a=35
a=1260/35=36
X*y-2=36
X*y=38 
Singurele nr.care dau 38 sunt 19 si 2
Adica-
x1-19
y1-2

x2-2 

y2-19
