Question

10+2z=18 solve for z

Answer 1

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 2

• 
  `\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`
