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 x = 10	\$ 1/x - 2x \$
2	Now substitute "x" value in the expression	\$ 1/10 - 2(10) \$
3	After multiplication we get	\$ 1/10 - 20 \$
4	Taking LCM as 10	\$ (1 - 200)/10 \$
5	After simplification we get	\$ -199/10 \$
6	Answer	B = \$ -199/10 \$

Steps

Problem

Solution

Determine the value of an expression by substituting the value
x = 10

\$ 1/x - 2x \$

Now substitute "x" value in the expression

\$ 1/10 - 2(10) \$

After multiplication we get

\$ 1/10 - 20 \$

Taking LCM as 10

\$ (1 - 200)/10 \$

After simplification we get

\$ -199/10 \$

Answer

B = \$ -199/10 \$
