120:y-23=17

To solve the equation 120 - y - 23 = 17, you need to isolate the variable y.

First, let's simplify the equation by combining like terms.

120 - y - 23 = 17

Combine the numbers on the left side of the equation:

97 - y = 17

Next, let's isolate the variable y by subtracting 97 from both sides of the equation:

97 - y - 97 = 17 - 97

On the left side, 97 - 97 cancels out:

-y = -80

To solve for y, divide both sides of the equation by -1:

y = 80

So the solution to the equation is y = 80.
