Find the values of x and y. (picture attached.)

Y=42 and x=7

Step-by-step explanation:

Referring that both angles equal each other we will us an = in both equations

2y-27=y+15

Subtract y from both sides

y-27=15

Now add 27 to both sides

y=42

Now check the solution

2(42)-27=57

(42)+15=57

So it is true! y equals 42!

3x+4=5x-10

Subtract 3x from both sides

4=2x-10

Now add 10 to both sides

14=2x

Now divide both sides by 2

7=x

Now check the solution

3(7)+4=25

5(7)-10= 25

so it is true x=7!

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
