The order that the pitcher threw is F, C, F, F, C, C, F, F, F then the next five pitches are C, C, C, C, F, F, F, F, F assuming the pitcher maintains this order
Subtract 12 from each side so it should look like this -12v=-2v-18 now add 2v to each side so it should look like this -10v=-18 now divdie each side by -10 and you should get v=9/5 or 1 4/5
