Determine whether the equation is true or false for the given below.
3x-y=14 when x=7 and y =7
Show work
To determine whether the equation is true or false, we substitute the given values of x and y into the equation and simplify.
Using x = 7 and y = 7, we substitute these values into the equation:
3(7) - 7 = 14
Simplifying further:
21 - 7 = 14
Now, we can see that 14 does not equal to 14.
Therefore, the equation is false when x = 7 and y = 7.
