64+х=92 х+78=97+3

To solve the first equation, 64 + x = 92, we need to isolate the variable x. To do this, we subtract 64 from both sides of the equation:

x = 92 - 64 x = 28

Therefore, x is equal to 28.

To solve the second equation, x + 78 = 97 + 3, we can simplify the equation by combining like terms:

x + 78 = 100

Now, we can isolate the variable x by subtracting 78 from both sides of the equation:

x = 100 - 78 x = 22

Therefore, x is equal to 22.
