Exploring Linear Equations with Multiple Variables

The video tutorial covers solving level three linear equations by simplifying and isolating variables. It demonstrates two example problems, showing how to move terms across the equation and verify solutions. The tutorial emphasizes understanding the process of combining like terms and using basic algebraic operations to solve equations.

What is the first step in solving a linear equation?

• Add the same number to both sides.

• Multiply both sides by the same number.

• Get all variables on one side and constants on the other.

• Divide both sides by the same number.

What is X plus 2X?

• 2X

• 3X

• 5X

• 4X

What do you get when you add 7X to both sides of the equation 3X + 3 = -7X - 5?

• 3X + 3 = 10X - 5

• 3X + 10X = -5

• 10X + 3 = -5

• 10X + 3 = 5

What is the result of dividing -8 by 10?

• -2/5

• -1/5

• -4/5

• -8/5

What is the simplified form of 5X - 7X?

• 12X

• -2X

• 2X

• -12X

What is the result of subtracting X from both sides of the equation -2X - 3 = X + 8?

• -3X - 3 = 8

• -X - 3 = 8

• -2X - 3 = 8

• X - 3 = 8

What is the result of dividing -3X by -3?

• -3X

• 3X

• X

• -X

What is the value of 5 times -11/3?

• -55/3

• 55/3

• -11/3

• 11/3

What is the simplified form of 3 in terms of a fraction with denominator 3?

• 9/3

• -9/3

• 6/3

• 3/3

What is the final solution to the equation 5X - 3 - 7X = X + 8?

• -11/3

• 3/11

• -3/11

• 11/3
