Question: Math homework problems PLZ help?
-3(7+3b)<-6b-3
2d-10>6(7-4d)
PLZ explain how u got the answers so I can understand.
Answer: You have to multiply the -3 to the 7 and the 3b remember since you are multiplying -3 X positive 3B the answer comes out to
-21-9B<-6b-3
you then add 9b to each side
-21<3b-3
add the - three
-18<3B
divide 3 on each side
-6 It's is practically the same for the other one D>2
here is the answer see if you can figure out if you can get it
remember you switch the sign to the opposite side if you divide by a negative
