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	\$ 7n − 5n + 10n − 4n = 64\$
2	Grouping like terms together	\$(7n + 10n) - (5n + 4n) = 64\$
3	After simplification	\$ 17n - 9n = 64 \$
4	After Subtraction	\$ 8n = 64\$
5	Dividing on both sides by '\$8\$' of the equality	\$cancel8^1/cancel8^1 n = cancel(64)^8/cancel(8)^1 \$
6	After cancelation	\$n = 8\$
7	Answer	A = \$n = 8\$

Steps

Problem

Solution

Solve

\$ 7n − 5n + 10n − 4n = 64\$

Grouping like terms together

\$(7n + 10n) - (5n + 4n) = 64\$

After simplification

\$ 17n - 9n = 64 \$

After Subtraction

\$ 8n = 64\$

Dividing on both sides by '\$8\$' of the equality

\$cancel8^1/cancel8^1 n = cancel(64)^8/cancel(8)^1 \$

After cancelation

\$n = 8\$

Answer

A = \$n = 8\$
