Answer:

Z=4

Explanation:

10+2z=18

Using inverse operations subtract 10 on both sides.

10+2z=18-10

-10

now we have:

2z÷2=8÷2

Divide by 2 to isolate z

Z=4

Answer:


  • \boxed{\sf z=4}

Explanation:


\sf 10+2z=18

Subtract 10 from both sides:-


\sf 10+2z-10=18-10

Simplify:-


\sf 2z=8

Divide both sides by 2:-


\sf \cfrac{2z}{2}=\cfrac{8}{2}


\sf z=4
