The values of the variables are given: a = 5 and b = 8. One of the expressions is correct, that is, the equation is true.
Let's test is one by one until we find the correct choice:
a)
8 + a + 8 + b = 104
Substitute the given values:
8 + 5 + 8 + 8 = 104
Operate:
29 = 104
This is a false equation.
b)
8 + a + 8b = 104
Substituting:
8 + 5 + 8(8) = 104
Operating:
13 + 64 = 104
77 = 104
This is false also
c)
8a + 8 + b = 104
Substituting:
8(5) + 8 = 104
40 + 8 = 104
48 = 104
This is a false i
