we're solving for z
so we subtract 4 from both sides
then the equation becomes
3z=30
divided 3 on both sides
z=10

3z + 4 = 34

Subtract 4 from both sides.

3z = 34 - 4

Simplify.

3z = 30

Divide both sides by 3.

z = 10

Check your work by plugging in 10 for z.

3z + 4 = 34

3(10) + 4 = 34

30 + 4 = 34

34 = 34 

So, z = 10

~Hope I helped!~
