Title: Solve the equation

Grade: 7-b Lesson: S2-L8

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

Lesson Steps

Steps	Problem	Solution
1	Solve	\$ n(2+1) + n(1+2) = 24 \$
2	After multiplication	\$ 2n + n + n + 2n = 24 \$
3	After Addition	\$ 6n = 24 \$
4	Dividing both sides by '\$ 6\$' of the equality	\$cancel6^1/cancel6^1 n = cancel(24)^4/cancel(6)^1 \$
5	After cancelation	\$ n = 4\$
6	Answer	A = \$ n = 4\$

Steps

Problem

Solution

Solve

\$ n(2+1) + n(1+2) = 24 \$

After multiplication

\$ 2n + n + n + 2n = 24 \$

After Addition

\$ 6n = 24 \$

Dividing both sides by '\$ 6\$' of the equality

\$cancel6^1/cancel6^1 n = cancel(24)^4/cancel(6)^1 \$

After cancelation

\$ n = 4\$

Answer

A = \$ n = 4\$
