Question

solve equation -5(b+7)=4(3b+4) how do you do it?

Answer 1

what do you get when you distribute -5(b+7)

Answer 2

so just distributing? -5b+35

Answer 3

close

Answer 4

but keep in mind that the negative distributes as well

Answer 5

oh ok so -5b-35

Answer 6

good, what about 4(3b+4)

Answer 7

12b+16

Answer 8

so we have this so far


-5(b+7)=4(3b+4)


-5b-35=12b+16

Answer 9

what's next?

Answer 10

combine like terms

Answer 11

are there any like terms?

Answer 12

think of each side as separate things for now (you can't combine across the equal sign)

Answer 13

-5b -35 = 12b+16
-5b -12b = 16+35
-17b = 51
b = -3

Answer 14

very good, you nailed it

Answer 15

that's what i was saying get the like terms on each side

Answer 16

then combine

Answer 17

ah i gotcha

Answer 18

Answer 19

I thought you meant combine the like terms in -5b-35=12b+16

Answer 20

but there aren't any because they are separated

Answer 21

but you got it though

Answer 22

oh ok

Answer 23

oh i was reading the wrong post...thought you were the OP
