For this case we have the following expression:

4 (3a + 7) +3 (2a + 5)

We must evaluate the expression for the following value:

a = 5

We have then:

4 (3 (5) +7) +3 (2 (5) +5)

Then, rewriting the expression we have:

4 (15 + 7) +3 (10 + 5)\\4 (22) +3 (15)\\88 + 45\\133

Answer:

The expression for a = 5 is given by:

4 (3a + 7) +3 (2a + 5) = 133
