Saxon Math Algebra 1/2 Review

What is an example of a variable term?

• 3x

• -1

• 2 x 3

• 1/2

Combine the like terms: 3x + 9x + 2 - x

• 11x + 2

• 13x + 2

• 12x + 2 - x

• 3x + 11

Solve: 3x + 3 = x - 5

• x = (-4)

• x = (-2)

• x = (-5)

• x = (-8)

Solve: 4x - 1 = x

• x = (1/5)

• x = (-1/5)

• x = (1/4)

• x = (-1/2)

How many terms are in 2x + x² + x + 2?

• 1 term

• 2 terms

• 3 terms

• 4 terms

Are 3 and 7, like terms?

• Yes

• No

Simplify -3x + 2y + 2x + 3 + 7

• x + 2y + 10

• -x + 2y + 10

• -5x + 2y + 10

• -3x + 2y + 5x + 7

Change this into an algebraic expression: A number decreased by 16.

• 1 + 16

• x + 16

• N + 16

• N - 16

Solve: 4x + 2 + 3x -2x = 12

• 5x + 2 = 12

• x = 2

• x = 12

• x = -2

If 2x + 4 = 6, what's the value of 3x -7?

• x = 1

• x = 4

• 1

• -4
