Title: Solve the equation

Grade: 7-b Lesson: S2-L2

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

Lesson Steps

Steps	Problem	Solution
1	Solve	\$ 12c - 1 = 0 \$
2	Adding '\$+1\$' on both sides	\$ 12c - \cancel1 + \cancel1 = 0 + 1 \$
3	After cancelation	\$ 12c = 1 \$
4	Dividing on both sides by '\$12\$' of the equality	\$ \cancel(12)^1/ \cancel(12)^1 c = 1/12 \$
5	After cancelation	\$ c = 1/12 \$
6	Answer	B = \$ c = 1/12 \$

Steps

Problem

Solution

Solve

\$ 12c - 1 = 0 \$

Adding '\$+1\$' on both sides

\$ 12c - \cancel1 + \cancel1 = 0 + 1 \$

After cancelation

\$ 12c = 1 \$

Dividing on both sides by '\$12\$' of the equality

\$ \cancel(12)^1/ \cancel(12)^1 c = 1/12 \$

After cancelation

\$ c = 1/12 \$

Answer

B = \$ c = 1/12 \$
