Using complete sentences, explain how solving a literal equation is similar to or different from simplifying an expression such as 6 - 2(52 + 7) � 4. (2 points)
Using complete sentences, explain what might happen if the order of operations was used to solve a literal equation. (1 point)

Answer 1

help please!!!

Answer 2

To solve for l in terms of the other literals, rewrite the given literal equation, using the distributive law of multiplication over addition:
p = 2l + 2w. Py the wymmetry property of equality we may rewrite it as
2l + 2w = p. Subtracting 2w from both sides to isolate the 2l results in
2l = p - 2w. Dividing both sides by 2 isolates i:
l = p/2 - w, and we have solved for l in terms of the other literals.

Answer 3

From the second row in the table we have p = 12 and w = 2. Substituting those numerical values into the last literl equation gives
l = 14/2 - 2, which evaluates to 5. That answers the first question in the table.
A similar calculation using the imformation in the third row will show that l = 3, answering the second question in the table.
