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!
