1B) write the question so it is readable

2A) 1/2 (16z - 12)= 1/3 (12z - 9)
1/2 (16z) - 1/2 (12)= 1/3 (12z) - 1/3(9)
8z - 6 = 4z - 3
subtract 4z from both sides
4z - 6 = -3
add 6 to both sides
4z (6 - 6= 0) = 6 - 3
4z = 3
divide both side by 4
z = 3/4 or .75

-4z -4z
4z-6=-3
+6 +6
4z=3
4z/4=3/4
z=3/4
