Question

1)-6*(x+-2x)=5x+8 2)50-|x|=25|x|-2 3)|x+3|/-8=1/-4 /- этот знак значит дробь решите уравнения

Answer 1

1)-6*(x+4)-(-3-2x)=5x+8
-6x-24+3+2x=5x+8
-4x-21=5x+8
-4x-5x=8+21
-9x=29
x=-29/9
2)50-|x|=25|x|-2
-|x|-25|x|=-2-50
-26|x|=-52
-26x=-52, x ≥ 0
-26*(-x)=-52,x < 0
x=2,x ≥ 0
x=-2,x < 0
x = 2
x =-2
x1=-2,x2=2
3)|x+3|/-8=1/-4
-4(x+3)=-8
x+3=2
x=2-3
x=-1

Answer 2

1) -6х-24+3+2х=5х+8;
-6х+2х-5х=8+24-3;
-9х=29;
х=29/-9; х=-3 2/9.

2)25|х|+|х|=50+2;
26|х|=52;
|х|=2; х=-2; х=2.

|х+3|/-8=1/-4;
|х+3|=2;
х+3=2; х=-1;
-(х+3)=2;
х+3=-2; х=-5.
