To evaluate the expression 3x + 6 - y when x = 2 and y = 5, substitute the given values of x and y into the expression:
3(2) + 6 - 5
Simplifying further:
6 + 6 - 5 = 12 - 5 = 7
Therefore, the value of the expression 3x + 6 - y when x = 2 and y = 5 is 7.
Evaluate the following expresion: 3x + 6 - y when x = 2 and y = 5
