What is the value of x?

x = 13

Step-by-step explanation:

To solve for x, we set equations (9x - 54) and (3x + 24) equal to each other because the angles are equal

(9x - 54) = (3x + 24); add 54 to both sides

9x = 3x + 78; subtract 3x from both sides

6x = 78; now divide by 6

x = 13

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
