Question

12+z=15? Help please

Answer 1

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

Answer 2

Hello there! :)

Answer:

z=3

*The answer must have a positive sign.*

Step-by-step 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!
