Question

Решите уравнения:
9x=8x-6-x
-1x+8=7+x-1
6-4у-1=у+3

Comments

9х=8х-6-х;2х=-6;х=-3

---

-1х-8=7+х-1;-2х=-8+6;х=-1

---

6-4y-1=y+3;-3y=-3;y=1

Answer 1

9х=7х-6
2х=-6
Х=-3

1+1=х+х
2=2х
Х=1

5-3=у+4у
2=5у
У=0,4

Answer 2

1. 9х=8х-6-х
9х-8х+х=-6
х=-3
2.-1х+8=7+х-1
-х-х=7-1-8
-2х=-2
х=1
3.6-4у-1=у+3
-4у-у=3-6+1
-5у=-2
у=0.4
