Respuesta :
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
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
