2|x-2|+3|y+1|=4
2x-y=3
dla 2|x-2|+3|y+1|=4 :
1) 2(x-2)+3(y+1)=4
2) 2(-x+2)+3(-y-1)=4
układy równań:
1)
2x-4+3y+3=4
-2x-3y=-5
-4y=-2
2x=y+3 =>x=(y+3)/2
y=1/2
x=7/4
2)
2(-x+2)+3(-y-1)=4
-2x+4-3y-3=4
-2x-3y=3
-4y=6
x=(y+3)/2
y=-6/4
x=(y+3)/2 => x=[(-3/2)+3]/2
y=-3/2
x=3/4
odp:x=7/4,y=1/2 i x=3/4,y=-3/2
