Question

Evaluate the given algebraic expression for x = 7 and y = 3.

2x + 2y

20
15
10
23

Answer 1

To evaluate the expression \(2x + 2y\) for \(x = 7\) and \(y = 3\), we can substitute the values of \(x\) and \(y\) into the expression.

First, substitute the values:

\[
2(7) + 2(3)
\]

Now, calculate each part:

\[
2(7) = 14
\]
\[
2(3) = 6
\]

Now, add those results together:

\[
14 + 6 = 20
\]

Therefore, the value of the expression \(2x + 2y\) when \(x = 7\) and \(y = 3\) is \(20\).

Thus, the answer is **20**.
