color(indigo)("Multiply 3 on both sides to get rid of the denominator:")Multiply 3 on both sides to get rid of the denominator:
4xx3=(5z+2)/cancel3xxcancel3
color(hotpink)("Subtract 2 on both sides to get the constant by itself:")
12 = 5z+2
-2 color(white)(aaaa) -2
10=5z
color(green)("Divide both sides by 5 to find z:")
10/5=(cancel5z)/cancel5
2=z
