Title: Determine the value of an expressions

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 y = -5	\$ 4y - 10/y \$
2	Now substitute "y" value in the expression	\$ 4(-5) - (10/(-5) ) \$
3	After multiplication we get	\$ -20 + \cancel10^2/\cancel5^1 \$
4	After cancellation we get	\$ -20 + 2 \$
5	After simplification we get	\$ - 18 \$
6	Answer	C = \$ - 18 \$

Steps

Problem

Solution

Determine the value of an expression by substituting the value
y = -5

\$ 4y - 10/y \$

Now substitute "y" value in the expression

\$ 4(-5) - (10/(-5) ) \$

After multiplication we get

\$ -20 + \cancel10^2/\cancel5^1 \$

After cancellation we get

\$ -20 + 2 \$

After simplification we get

\$ - 18 \$

Answer

C = \$ - 18 \$
