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	\$ 10n + 1 3/2 = 3 \$
2	After simplification	\$ 10n + 5/2 = 3 \$
3	Move constant term to the right side	\$ 10n = 3 - 5/2 \$
4	Taking LCM as '\$2\$'	\$ 10n = (6 - 5)/2 \$
5	After simplification	\$ 10 n = 1/2 \$
6	Dividing on both sides by '\$10\$' of the equality	\$ \cancel(10)^1/ \cancel(10)^1 n = (1/2)/10 \$
7	After cancelation	\$ n = 1/20 \$
8	Answer	D = \$ n = 1/20 \$

Steps

Problem

Solution

Solve

\$ 10n + 1 3/2 = 3 \$

After simplification

\$ 10n + 5/2 = 3 \$

Move constant term to the right side

\$ 10n = 3 - 5/2 \$

Taking LCM as '\$2\$'

\$ 10n = (6 - 5)/2 \$

After simplification

\$ 10 n = 1/2 \$

Dividing on both sides by '\$10\$' of the equality

\$ \cancel(10)^1/ \cancel(10)^1 n = (1/2)/10 \$

After cancelation

\$ n = 1/20 \$

Answer

D = \$ n = 1/20 \$
