Answer:
z = -2
Step-by-step explanation:
First, use the Distributive property to Multiply 4*3z. Do the same to 4*5. You should now have 12z + 20 = -4
Next, you want to isolate the variable. To do that, start by Subtracting 20 from both sides of the equation sign. You should now have 12z = -24
Last, Divide each side by 12. You should now have z = -2
I hope this helps!
