Solving Linear Equations and Expressions

The video tutorial explains how to solve a mathematical problem involving equations. It starts by setting up the problem with given equations, x - y = 3 and y - z = 3. By adding these equations, the video demonstrates how to simplify and solve for x - z, leading to a denominator of 6 squared. The tutorial then evaluates the expression 3 squared plus 3 squared, divided by 36, simplifying to one-half. The correct answer is identified as option D.

What is the initial value given for both x minus y and y minus C?

• Four

• Five

• Three

• Two

Which two equations are formed from the given information?

• x minus y equals four and y minus Z equals four

• x minus y equals three and y minus Z equals three

• x minus y equals two and y minus Z equals two

• x minus y equals five and y minus Z equals five

What happens to the y terms when the two equations are added together?

• They double

• They cancel each other out

• They remain unchanged

• They become negative

What is the value of 3 squared plus 3 squared?

• 15

• 9

• 18

• 12

What is the simplified form of 18 divided by 36?

• One-third

• Two-thirds

• One-fourth

• One-half
