Question

3 równania do rozwiazania :) :p
{4x+2y=10
{x+2y=5
drugie ..
{3(x+y)-2(y+3)=y+3(x-2)
{x-2y=5
i trzecie ;D
{x+2 /5-2y=5
{x- (y+2)/6 =3
z góry dzięki hehe ;)
te { to ta klamerka jak coś co jest przy rownaniach

Answer 1

{4x+2y=10
{x+2y=5
{4x+2y=10
{x=5-2y
4(5-2y)+2y=10
20-8y+2y=10
-6y=-10
y=10/6
y=1i4/6
y=1i2/3
x+2*(10/6)=5
x+20/6=5
x=5-3i1/3
x=1i2/3
y=1i2/3

{3(x+y)-2(y+3)≠y+3(x-2)
{x-2y=5
{3x+3y-2y+3≠y+3x-6
{x-2y=5
3x-3x+3y-2y-y≠-6-3
0≠-9

{x+2/5 -2y=5
{x-(y+2)/6=3
{x=4i3/5 + 2y
{x=3i2/6+y/6
4i3/5+2y=3i2/6+y/6
4i18/30+60y/30=3i10/30+5y/30
55y/30=-1i8/30
55y=-38
y=-38/55
