Title: Solve the equation

Grade: 7-b Lesson: S2-L6

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

Lesson Steps

Steps	Problem	Solution
1	Solve	\$ 15/8 s + 8 = 18 - 1/8 s \$
2	Move Variable terms to the left side and constant terms to the right side	\$ ((15s)/8) + ((s)/8) = 18 - 8 \$
3	Taking LCM as '\$8\$'	\$ (15s + s)/8 = 10/1\$
4	By using cross multiplication	\$ 15s + s = 80\$
5	After Addition	\$ 16s = 80 \$
6	Dividing on both sides by '\$16\$'of the equality	\$ \cancel(16)^1/ \cancel(16)^1 s = \cancel80^(5)/\cancel16^1 \$
7	After cancelation	\$ s = 5 \$
8	Answer	D = \$ s = 5 \$

Steps

Problem

Solution

Solve

\$ 15/8 s + 8 = 18 - 1/8 s \$

Move Variable terms to the left side and constant terms to the right side

\$ ((15s)/8) + ((s)/8) = 18 - 8 \$

Taking LCM as '\$8\$'

\$ (15s + s)/8 = 10/1\$

By using cross multiplication

\$ 15s + s = 80\$

After Addition

\$ 16s = 80 \$

Dividing on both sides by '\$16\$'of the equality

\$ \cancel(16)^1/ \cancel(16)^1 s = \cancel80^(5)/\cancel16^1 \$

After cancelation

\$ s = 5 \$

Answer

D = \$ s = 5 \$
