Steps to solve:
2 + 3(z - 3) = z + 3z + 6z
~Distribute left side and simplify right side
2 + 3z - 9 = 10z
~Simplify left side
3z - 7 = 10z
~Subtract 3z to both sides
-7 = 7z
~Divide 7 to both sides
-1 = z
Best of Luck!
Answer:
z=-1
Step-by-step explanation:
2+3(z-3)=z+3z+6z
2+3z-9=z+3z+6z
2+3z-9=10z
2-9=10z-3z
-7=7z
7 7
Proof:
2+3(-1-3)=-1+(-3)+(-6)
2+3(-4)=-1-3-6
2-12=-10
-10=-10
