For this case we have the following expression:
[tex]a + b[/tex]
We must evaluate the expression to:
[tex]a = 2\\b = 3[/tex]
Substituting the values in the expression we have:
[tex]2 + 3[/tex]
Equal signs are added and the same sign is placed.
So:
[tex]2 + 3 = 5[/tex]
Finally, the value of the expression is 5.
Answer:
[tex]a + b = 5[/tex]for[tex]a = 2[/tex] and[tex]b = 3[/tex]
