One step :
3+n = 6
-3+3+n=6-3
n = 3

3+n=6
3+3=6
6=6

Question Two:

m - 9 = -13
+ 9 + 9

m = -4
m - 9 = -13
(-4)-9 -13
-13 = -13
























Question Three:

2x =6
/2 /2
1x =3
x =3
2x=6
2(3)=6
6=6

















Question Four:
x/2 = 3
(2)x/2=3(2)
x=6
x/2=3
6/2=3
3=3

Two Step:

Question One:

2x + 1 = 5
2x +1-1 =5-1

2x = 4
2 2

x = 2
2x+1=5
2(2)+1=5
5=5
