Question

12+z=15? Help please

Answer 1

Hello there! :)

Answer:

z=3

*The answer must have a positive sign.*

Explanation:

First, switch sides of an equation.

`z+12=15`

Then, you subtract by 12 from both sides of an equation.

`z+12-12=15-12`

And finally, simplify and solve. You can also subtract by the numbers.

`15-12=3`

`12+3=15`

`15-3=12`

`3+12=15`

Answer:
`z=3`

Hope this helps!

Thanks!

Answer 2

Isolate x by subtracting 12 on both sides to get x=3. You can plug it in to check. Hopefully I helped. :)
