Determine if the expressions are equivalent. when w = 11:

2w + 3 + 4 4 + 2w + 3

2(11) + 3 + 4 4 + 2(11) + 3

22 + 3 + 4 4 + 22 + 3

25 + 4 26 + 3

29 29

Complete the statements.

Now, check another value for the variable.

When w = 2, the first expression is
.
When w = 2, the second expression is
.
Therefore, the expressions are
.
