Grade: 6-b Lesson: S3-L10

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

Lesson Steps

Steps	Problem	Solution
1	Determine the value of an expression by substituting the value n = 2	\$ 3/n - 5n \$
2	Now substitute "n" value in the expression	\$ 3/2 - 5(2) \$
3	After multiplication we get	\$ 3/2 - 10 \$
4	Taking LCM as 2	\$ (3 - 20)/2 \$
5	After simplification we get	\$ -17/2 \$
6	Answer	D = \$ -17/2 \$

Steps

Problem

Solution

Determine the value of an expression by substituting the value
n = 2

\$ 3/n - 5n \$

Now substitute "n" value in the expression

\$ 3/2 - 5(2) \$

After multiplication we get

\$ 3/2 - 10 \$

Taking LCM as 2

\$ (3 - 20)/2 \$

After simplification we get

\$ -17/2 \$

Answer

D = \$ -17/2 \$
