Answer:

x = 23

Step-by-step explanation:

3x + 7 = x + 53 because vertical angles are congruent. So just solve...

3x - x + 7 = x + 53 - x

2x + 7 = 53

2x + 7 - 7 = 53 - 7

2x = 46

x = 23

Hey there! :)

Answer:

y = 11.

Step-by-step explanation:

Set both of the equations equal:

5x - 9 = x² - 3x + 7

Rearrange the equation:

0 = x² - 3x - 5x + 9 + 7

Combine like terms:

0 = x² - 8x + 16

Factor:

0 = (x -4)²

Solve for x:

0 = x - 4

x = 4.

Plug this into an equation to solve for 'y':

y = 5(4) - 9

y = 20 - 9

y = 11.
