What is r minus 2s equals 14 for s

If you mean this:

r - 2s and s equals 14

plus 14 in for s

r-2 (14)

so solve you can multiply 2 by 14 to get 28

r-28

if this is the other type of algebra question where you can't leave it unsolved you can make it an equation to solve for r

r-28=0

add 28 to both sides to get r alone

r=28
