0=0.6x-3.6
.6x=3.6
x=3.6/.6
x=6 ans.
-----------------
6-8x=-26
-8x=-26-6
-8x=-32
x=-32/-8
x=4 ans.
----------------
5=5x+27-4
5x=5-27+4
5x=-28
x=-28/5 ans.
-------------------
3(w+3)=-15
3w+9=-15
3w=-15-9
3w=-24
w=-24/3
w=-8 ans
-----------------
2(y+1)-5=7
2y+2-5=7
2y=7-2+5
2y=10
y=10/2
y=5 ans.
-------------------
6-2/3x=-8
6-2x/3=-8
-2x/3=-8-6
-2x/3=-14
-2x=3*-14
-2x=-42
x=-42/-2
x=21 ans.
------------------
0.3x-4.2=2.7
.3x=2.7+4.2
.3x=6.9
x=6.9/.3
x=23 ans.
