To solve the equation, we need to isolate the variable x.
Moving x terms to one side and constants to the other side:
73 - 69x = 100 - 78x
Add 78x to both sides:
73 + 9x = 100
Subtract 73 from both sides:
9x = 27
Divide by 9 on both sides:
x = 3
Therefore, the answer to the equation is x = 3.
Now we plug back the value of x into the equation:
73 - 69(3) = 100 - 78(3)
73 - 207 = 100 - 234
-134 = -134
Since both sides of the equation are equal, the equation is an identity.
