Question

Решите уравнение:

№2. -1/6х = 2. №3. 5 + 2х = 0
№4. 2х + 6 =3 + 5х №5. (х – 3) – (3х – 4) = 15.

Answer 1

№4
2х+6=3=5х
2х-5х=3-6
-3х=-3
-х=1
х= -1

№5 

(х-3)-(3х-4)=15
Х-3-3Х+4=15
-4х+1=15
-4х=16
-х=4
х=-4

Answer 2

-1/6x=2
x=2÷(-1/6)
x=-2×6/1
x=-12
$$$$$$$$$
5+2x=0
2x=0-5
2x=-5
x=-5÷2
x=-2.5
$$$$$$$$$$
2x+6=3+5x
6-3=5x-2x
3x=3
x=3÷3=1
$$$$$$$$'$'
(x-3)-(3x-4)=15
x-3-3x+4=15
-2x+1=15
-2x=15-1
-2x=14
x=14÷(-2)
x=-7
