Answer 1

A )
x/2 -5 = 3
x/2= 3+5
x/2=8
x=2*8
x=16...
--------------------
B)
8 - x/3 =2
-x/3=2-8
-x/3=-6
-x=-6*3
-x=-18
x=18
------------------
C)
x/3-1/3=x/2+3
x/3-x/2=3+1/3
2x/6 -3x/6 =3 1/3
-x/6=10/3
-3x=60
x=-20

D)
-2x/3+2=5x/6-3x/2
-2x/3 - 5x/6 + 3x/2=-2
-4x/6 - 5x/6 + 9x/6=-2
-9x/6+9x/6=-2
0=-2

E)

 - 5x =10

-5x=10


Semua dikali 3 = 3( -5x =10)
3(() 3( -5x ) =3(10) 
2x-4 - 15x =30
2x-15x=30+4
-13x=34
x=34/-13
x=-34/13

x=

F)



3x-15=7(6+2x)
3x-15=42+14x
3x-14x=42+15
-11x=57
x=57/-11
x=-57/11

x=
