Title: Determine the value of an expression

Grade: 6-b Lesson: S4-L1

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 values x = 1,y = 5,z = -3	\$x/y-3z \$
2	Now substitute "x,y,z" values in the expression	\$ 1/5 - 3(-3) \$
3	After simplification we get	\$ 1/5 + 9 \$
4	Taking LCM as 5	\$ (1 + 45)/5 \$
5	After simplification we get	\$ 46/5 \$
6	Answer	D = \$ 46/5 \$

Steps

Problem

Solution

Determine the value of an expression by substituting the values
x = 1,y = 5,z = -3

\$x/y-3z \$

Now substitute "x,y,z" values in the expression

\$ 1/5 - 3(-3) \$

After simplification we get

\$ 1/5 + 9 \$

Taking LCM as 5

\$ (1 + 45)/5 \$

After simplification we get

\$ 46/5 \$

Answer

D = \$ 46/5 \$
