Answer: x = 10 y=20
Step-by-step explanation:
You can answer this question by plugging in each equation:
2x=y, x+y=30. Let us plug y as 2x in the second equation x+y=30
x+2x= 30
3x= 30
x=10
After we found x we can then find y by plugging the 10 for x.
2(10) = y
y =20
or you could plug in the other equation
10+y=30
subtract 10 from 30 and we get 20
to double check we can plug in both numbers
2(10) = 20 which is correct
and 10 + 20 = 30 which is correct

Answer:
4.) Choice B
&
5.) Choice A
Step-by-step explanation:
<em><u>Question 4:</u></em>
First you have to solve for y to get slope intercept form.

The slope is a fraction but you need it to convert it to a decimal so that'll be Choice B.
<em><u>Question 5:</u></em>
For this one I we will use this formula 
I will choose the easy pairs to plug it in 

The slope is a fraction again but you can convert it and that'll be Choice A.
