Now, find the value of the second expression when a=2 and b=1. Start by substituting, then evaluate the expression.
4a + 6b
=

Answer 1

To evaluate the expression \( 4a + 6b \) when \( a = 2 \) and \( b = 1 \), we can substitute the values of \( a \) and \( b \) into the expression:

\[
4a + 6b = 4(2) + 6(1)
\]

Now, calculate each term:

\[
4(2) = 8
\]
\[
6(1) = 6
\]

Adding these together:

\[
8 + 6 = 14
\]

Thus, the value of the expression \( 4a + 6b \) when \( a = 2 \) and \( b = 1 \) is \( \boxed{14} \).
