Title: Solve the equation

Grade: 7-b Lesson: S2-L7

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

Lesson Steps

Steps	Problem	Solution
1	Solve	\$ 10(3 - x/10)= -5(x-5) \$
2	After simplification	\$ 30 - \cancel10x/\cancel(10) = - 5x + 25 \$
3	After cancellation	\$ 30 - x = -5x + 25 \$
4	Move Variable terms to the left side and constant terms to the right side	\$ 5x - x = 25 - 30 \$
5	After Subtraction	\$ 4x = - 5 \$
6	Dividing on both sides by "4" of the equality	\$ \cancel(4)^1/ \cancel(4)^1 x = -5/4 \$
7	After cancelation	\$ x = - 5/4 \$
8	Answer	A = \$ x = - 5/4 \$

Steps

Problem

Solution

Solve

\$ 10(3 - x/10)= -5(x-5) \$

After simplification

\$ 30 - \cancel10x/\cancel(10) = - 5x + 25 \$

After cancellation

\$ 30 - x = -5x + 25 \$

Move Variable terms to the left side and constant terms to the right side

\$ 5x - x = 25 - 30 \$

After Subtraction

\$ 4x = - 5 \$

Dividing on both sides by "4" of the equality

\$ \cancel(4)^1/ \cancel(4)^1 x = -5/4 \$

After cancelation

\$ x = - 5/4 \$

Answer

A = \$ x = - 5/4 \$
