Combining Like Terms in Algebra

The video tutorial explains the process of eliminating variables in equations by adding them together. It provides two examples where like terms are combined to simplify the equations, resulting in the elimination of one variable. The first example simplifies to -4x = 4, and the second example simplifies to -17y = 17.

What is the result of combining the terms -8x and 4x?

• -4x

• 0

• -12x

• 4x

When -10y and 10y are combined, what is the result?

• 20y

• 0

• -20y

• 10y

What is the simplified form of the equation -4x = 4?

• x = 4

• x = -1

• x = 1

• x = -4

In the second example, what is the result of combining 5x and -5x?

• -10x

• 5x

• 0

• 10x

What is the result of combining -7y and -10y in the second example?

• 3y

• -17y

• -3y

• 17y
