Title: Solve the equation

Grade: 7-b Lesson: S2-L5

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

Lesson Steps

Steps	Problem	Solution
1	Solve	\$ 25n + 12/4 = 8 \$
2	After simplification	\$ 25n + \cancel12^3/\cancel4^1 = 8 \$
3	After cancelation	\$ 25n + 3 = 8 \$
4	Move constant term to the right side	\$ 25n = 8 - 3 \$
5	After simplification	\$ 25 n = 5 \$
6	Dividing on both sides by '\$25\$' of the equality	\$ \cancel(25)^1/ \cancel(25)^1 n = \cancel(5)^1/ \cancel(25)^5 \$
7	After cancelation	\$ n = 1/5 \$
8	Answer	C = \$ n = 1/5 \$

Steps

Problem

Solution

Solve

\$ 25n + 12/4 = 8 \$

After simplification

\$ 25n + \cancel12^3/\cancel4^1 = 8 \$

After cancelation

\$ 25n + 3 = 8 \$

Move constant term to the right side

\$ 25n = 8 - 3 \$

After simplification

\$ 25 n = 5 \$

Dividing on both sides by '\$25\$' of the equality

\$ \cancel(25)^1/ \cancel(25)^1 n = \cancel(5)^1/ \cancel(25)^5 \$

After cancelation

\$ n = 1/5 \$

Answer

C = \$ n = 1/5 \$
