Title: Solve the equation

Grade: 7-b Lesson: S2-L3

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

Lesson Steps

Steps	Problem	Solution
1	Solve	\$ 14d + 29 = 85 \$
2	Adding '\$-29\$' on both sides	\$ 14d + \cancel29 - \cancel29 = 85 - 29 \$
3	After cancelation	\$ 14d = 56 \$
4	Dividing on both sides by '\$14\$' of the equality	\$ \cancel(14)^1/ \cancel(14)^1 d = \cancel(56)^4/ \cancel(14)^1 \$
5	After cancelation	\$ d = 4 \$
6	Answer	B = \$ d = 4 \$

Steps

Problem

Solution

Solve

\$ 14d + 29 = 85 \$

Adding '\$-29\$' on both sides

\$ 14d + \cancel29 - \cancel29 = 85 - 29 \$

After cancelation

\$ 14d = 56 \$

Dividing on both sides by '\$14\$' of the equality

\$ \cancel(14)^1/ \cancel(14)^1 d = \cancel(56)^4/ \cancel(14)^1 \$

After cancelation

\$ d = 4 \$

Answer

B = \$ d = 4 \$
