Question

Solve for z: 2+3(z-3) = z+3z+6z

Answer 1

z=-1

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

z=-1

Proof:

2+3(z-3)=z+3z+6z

2+3(-1-3)=-1+(-3)+(-6)

2+3(-4)=-1-3-6

2-12=-10

-10=-10

Answer 2

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!
