How do I extract the x values from the following list and divide them
by 2:

{{120.664, {x -> -4.64844}}, {
        118.131, {x -> -4.4542}}, {115.479, {x -> -4.25828}}, {
        112.697, {x -> -4.06053}}, {109.766, {x -> -3.8606}}, {
        106.666, {x -> -3.65812}}, {
  103.372, {x -> -3.45257}}, {99.8501, {x -> -3.24323}}, {
  96.0571, {x -> -3.02915}}, {
        91.9343, {x -> -2.80902}}, {87.3996, {x -> -2.58106}}, {
        82.3355, {x -> -2.34305}}, {76.5712, {x -> -2.09251}}, {
        69.8594, {x -> -1.8273}}, {61.8567, {x -> -1.54659}}, {
        52.1348, {x -> -1.25235}}, {40.3287, {x -> -0.952531}}, {
        26.7404, {x -> -0.66784}}, {13.703, {x -> -0.434276}}, {
        5.08285, {x -> -0.270745}}, {1.45243, {x -> -0.152066}}}
