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 + 2n + 3n + 5n = 121 \$
2	After Addition	\$11n = 121\$
3	Dividing on both sides by \$11\$' of the equality	\$cancel(11)^1/cancel(11)^1 n = cancel(121)^11/cancel(11)^1 \$
4	After cancelation	\$ n = 11\$
5	Answer	c = \$n = 11\$

Steps

Problem

Solution

Solve

\$ n + 2n + 3n + 5n = 121 \$

After Addition

\$11n = 121\$

Dividing on both sides by \$11\$' of the equality

\$cancel(11)^1/cancel(11)^1 n = cancel(121)^11/cancel(11)^1 \$

After cancelation

\$ n = 11\$

Answer

c = \$n = 11\$
