color(green)(z = 2")z=2

Explanation:

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
