Title: Find the variable value of equation

Grade: 7-a Lesson: S1-L2

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

Lesson Steps

Step	Type	Explanation	Answer
1	Problem	Solve the equation: 33 xy - 23= 12 xy - 2
2	Hint	Moving constant term to right side and variable term to left side we get	33 xy - 12 xy = 23 - 2
3	Step	Taking variable terms common	xy ( 33 - 12 ) = 23 - 2
4	Step	After Subtraction	21 xy = 21
5	Step	Dividing with 21 on both sides	\$ (\cancel(21)xy)/\cancel(21) = \cancel(21)^1/\cancel(21)^1 \$
6	Step	After Division	xy = 1

Explanation

Answer

Problem

Solve the equation:
33 xy - 23= 12 xy - 2

Hint

Moving constant term to right side and variable term to left side we get

33 xy - 12 xy = 23 - 2

Step

Taking variable terms common

xy ( 33 - 12 ) = 23 - 2

Step

After Subtraction

21 xy = 21

Step

Dividing with 21 on both sides

\$ (\cancel(21)xy)/\cancel(21) = \cancel(21)^1/\cancel(21)^1 \$

Step

After Division

xy = 1
