Question

I need help with this practice Since I am relatively new to this branch/topic of math, can you explain it to me step-by-step as you solve?

Answer 1

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
