r+2s/2=6+t r+s=6+t (Divide 2s by 2 giving you just 2) r=6+t-s (subtract s from both sides positive s and negative s cancel out leaving only r on the left and negative s on the right.) the answer is r=6+t-s
r + 2 2 s = 6 + t ∣ s u b t r a c t 2 2 s r = 6 + t + 2 2 s r = 6 + t + s A n s w er i s r = 6 + t + s .
To solve the equation 2 r + 2 s = 6 + t , we multiply both sides by 2, resulting in r + 2 s = 12 + 2 t . By isolating r , we find r = 2 t − 2 s + 12 . This expression gives us the value of r in terms of s and t .
