Question

Solve this plz
z = 2a + 2. for a

Answer 1

a=(z-2)/2

Explanation:

You need to isolate your "a" variable so first you want to subtract 2 from both sides, leaving you with:

z-2=2a

then you want to divide by 2 on both sides to isolate your "a" variable which would leave you with

a=
`((z-2))/(2)`
