1.b-3x=x+1
        +3x
b=4x+1 if u r solving for b but if u r solving for x..

Hello Ms,
A) b = 4x + 1
OR 4x = b-1
So x = (b-1)/4
B) -3x -x = 1-1 = 0
So -4x = 0
Hence x = 0
C) 3h - 2h = 1+8 = 9
So h = 9

b - 3x = x + 1
+3x = +3x
b = 4x + 1
-1 = -1
b - 1 = 4x
/4 = /4
(b-1)/4 = x

B) -3x+1 = x+1
+3x = +3x
1 = 4x + 1
-1 = -1
0 = 4x
/4 = /4
0 = x

C) 3h - 8 = 1+2h
-2h = -2h
h - 8 = 1
+8 = +8
h = 9
