2(4 - 2r) = -2(r + 5)
First, divide both sides by -2. / Your problem should look like: \(-4 + 2r = r + 5\)
Second, regroup your terms. / Your problem should look like: \(2r - 4 = r + 5\)
Third, add 4 to both sides. / Your problem should look like: \(2r = r + 5 + 4\)
Fourth, add r + 5 + 4 to get r + 9. / Your problem should look like:\(2r = r + 9\)
Fifth, subtract r from both sides. / Your problem should look like: \(2r - r = 9\)
Sixth, subtract 2r - r to get r. / Your problem should look like: \(r = 9\)
Answer: r = 9
