Question

What is the second step to solve the equation below x=
`(1)/(2)`(y+z) for y

Answer 1

We have the equation

`x=(1)/(2)(y+z)`

And we have to solve it for y. The first step to do this is to get rid of the 2 that is dividing. To do that we should remember, if something is dividing we take to the other side multiplying. This is

`2x=y+z`

The second step to solve the equation is to get rid of the z, since it is adding we take it to the other side substracting. Then

`y=2x-z`
