Question

How do i work this? y= x+4
-3 + 2y = 8

Answer 1

substitute x + 4 for y in the second equation

Answer 2

so -3 + 2(x + 4) = 8

Answer 3

then use the distributive property, combine like terms, and solve for x

Answer 4

so you would do -3+2 which = -1? then the rest is distrubitive property?

Answer 5

no, distributive property first. distribute the 2 into the parentheses

Answer 6

oh so 2x+8 then what lol sorry i suck at math.

Answer 7

so then our equation would be -3 + 2x + 8 = 8

add like terms

Answer 8

@ForevernAlways you should check that what you wrote in your question is actually the problem you are working on.

Answer 9

mmm i would you put that? bc u alredi put +8 but then you added =8....im confused Dx

Answer 10

this was our equation to begin with: -3 + 2(x + 4) = 8. after distributing the 2, we get -3 + 2x + 8 = 8

Answer 11

okay lol so after you get that, you combine -3 and 8?

Answer 12

yep

Answer 13

are you good now? or do you need help still?

Answer 22

just ask me for help

Answer 23

Answer 25

is x=-1.5 right

Answer 26

lol i love hogwarts <3

Answer 27

it would just be 1.5. no negative

Answer 28

do you have to find out what y equals too?

Answer 29

oh okay thanks for the help <3
oh dang yeah i do, how do i do that. Sorry im re taking algebra on the computer and its so much harder then regular at skwl and plus im takin geometry lol

Answer 30

all you have to do is add 1.5 and 4. since we know that y = x + 4 and x = 1.5

Answer 31

ohhh yay harldy no work hehe.

Answer 32

yep :) all the work went into finding out what x was lol

Answer 33

yep xD
