Subtract 10 from 10-7b>10, and -7b>10, you want to get the negative 7b to a positive 7b. So you multiply both sides by -1 and you flip the sign. 7b<0 and you make 7 less than 0 you want to multiply it by a negative, bo b would be a negative. -2<0; b<-2
Now for the 5b-6>-11
Add 6 to -6 and -11. 5b>-5
You divide -5 by 5 to isolate the variable. -2>b>-1
