Question

simplify -4(-3y-v)+5(5v-y)

Answer 1

do you know how to expand those brackets?

Answer 2

@bluebrandon no

Answer 3

ok so -4(-3y-v) means you multiply everything inside the brackets by -4

so you would get -4(-3y-v) = (-4)(-3v) - (-4)(v)

Answer 4

you would do the same thing for the 5(5v-y)

Answer 5

then all you need to do is collect like terms

Answer 6

@bluebrandon what's the answer

Answer 7

what have you got after doing what I said?

Answer 8

technically use distributive properties and combining like terms

Answer 9

@bluebrandon is the answer -12v-4v+25vy

Answer 10

not quite for the first part -4(-3y-v) = (-4)(-3v) - (-4)(v)
should give you 12v +4v
you shouldn't have any terms with vy either

Answer 11

i got 7y=29v how is it different please tell me

Answer 12

12+4v+25y @bluebrandon is that it?

Answer 13

ok you seem to be having some difficulty I will show you the answer and if you have any questions about what is going on please ask.

-4(-3y-v)+5(5v-y)
= (-4)(-3y) - (-4)(v) + 5(5v) - 5(y)
= 12y + 4v + 25v -5y
= 7y +29v

Answer 14

the last line is where we collected the like terms together

Answer 15

ok, got it, thx
