Explanation: Hello Students, time to practice and review the steps for the problem.

Lesson Steps

Steps	Problem	Solution
1	Solve	\$ 20 = 2(n - 3) + 8 \$
2	After Simplification	\$ 20 = 2n - 6 + 8 \$ \$ 2n - 6 + 8 = 20\$
3	Move constant terms to the right side	\$ 2n = 20 + 6 - 8 \$
4	After Simplification	\$ \cancel(2)^1n = \cancel18^9 \$
5	After cancellation	\$ n = 9\$
6	Answer	A = \$ n = 9 \$

Steps

Problem

Solution

Solve

\$ 20 = 2(n - 3) + 8 \$

After Simplification

\$ 20 = 2n - 6 + 8 \$

\$ 2n - 6 + 8 = 20\$

Move constant terms to the right side

\$ 2n = 20 + 6 - 8 \$

After Simplification

\$ \cancel(2)^1n = \cancel18^9 \$

After cancellation

\$ n = 9\$

Answer

A = \$ n = 9 \$
