Answer:
3
Step-by-step explanation:
4[z+3(z-1)]=36
z+3(z-1)=36/4
z+3z-3=9
4z-3=9
4z=9+3
4z=12
z=12/4
z=3
Answer:
4z+2(square)2z=2(square)6
Step-by-step explanation:
4((z+3(z-1)))=36
4(z^2-z+3((z-3)))=36
4(z^2-z+3z-3)=36
4((z^2+(-z+3z)-3))=36
4(z^2+2z-3)=36
4z^2+8z-12=36
4z^2+8z=24
((4(square)z^2))+(square)8z=(square)24
4z+2(square)2z=2(square)6
