You’re trying to get the first equation to equal y so you can substitute it in the second question
2x + y = -2
subtract 2x from both sides: y = -2 - 2x
rearrange the equation : -2x -2
so the answer is C
?????? Is there a picture? I can’t see it if there is :)
Answer:
y= ? / ? x
==> y = 12/3 x
y = 4x
Step-by-step explanation:
K = 4
Unit rate means one. So the best way to solve this is using a proportion over one. If there are 258 pencils in 3 purses 258/3 then how many are in one purses x/1. Cross multiply next.
258/3 * x/1. You get 3x and 258. To get the x alone, divide both sides by three. Your answer is 86 pencils in one purse.
