Title: Determine the value of an expression by substituting the values

Grade: 6-b Lesson: S4-L5

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 p = -2	\$(6+p)/(21-5) \$
2	Now substitute "p" value in the expression	\$ (6+(-2))/((-2)-10) \$
3	After simplification we get	\$ (6-2)/(-2-10) \$
4	After simplification we get	\$ \cancel4^1/\cancel(-12)^3 \$
5	After cancellation we get	\$ -1/3 \$
6	Answer	D = \$ -1/3 \$

Steps

Problem

Solution

Determine the value of an expression by substituting the value
p = -2

\$(6+p)/(21-5) \$

Now substitute "p" value in the expression

\$ (6+(-2))/((-2)-10) \$

After simplification we get

\$ (6-2)/(-2-10) \$

After simplification we get

\$ \cancel4^1/\cancel(-12)^3 \$

After cancellation we get

\$ -1/3 \$

Answer

D = \$ -1/3 \$
