To solve the equation -a + 28 = 14, you need to isolate the variable, which is "a".
First, subtract 28 from both sides of the equation:
-a + 28 - 28 = 14 - 28
-a = -14
Next, multiply both sides of the equation by -1 to eliminate the negative sign in front of "a":
(-1)(-a) = (-1)(-14)
a = 14
The solution to the equation is a = 14.
-a + 28 = 14
