Question

Can someone help me with this I’m in the middle of a test and really don’t know what I’m doing

Answer 1

Answer:

x = 9

Step-by-step explanation:

they are equal to each other

3x + 15 = 5x - 3

subtract 3x from borh sides

15 = 2x -3

add 3 to both sides

18 = 2x

divid both sides by 2

9 = x

Answer 2

Answer:

x=9

Step-by-step explanation:

Since they are corresponding angles, they are the same value. We can then put these two equations equal to each other and solve for x.
