Adding and Subtracting Linear Expressions

Combine like terms to simplify:
 (5x + 2) + (4x + 5)

• 9x -7

• -9x-11

• 9x+7

• x+7

Give the correct name for 
-3x+2

• Cubic Binomail

• Linear Monomial

• Linear Binomial

• Cubic monomial

Add or Subtract to Simplify:
(4x²+ x) - (x²+ 2x)

• 3x² - x

• 4x² + 2x

• 3x² + 3x

• 3x² + 2x

x - 62 = 123
How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side. 

• Subtract 62 from each side.

• Multiply each side by 62.

• Add 123 to each side.

f(x)= 4x-7g(x)= 6x-8Find f(x)+g(x) (a)  

• 2x+15

• 10x-15

• -2x-15

• 10x+1

Solve for x:
3(5x + 10) + 10 = 6x - (x + 10)

• 3

• -3

• -5

• 5

Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step

• They should add 19 instead of subtracting 19

• I can not find an error

• Instead of adding 3k they should subtract 3k

Add or Subtract to Simplify:
 (5x + 2) + (4x + 5)

• 9x -7

• -9x-11

• 9x+7

• x+7

Simplify by combining like terms:
5a + 2b - 3a + 4

• 8a + 2b + 4

• 2a + 2b + 4

• 8ab

• 4ab + 4

Add or Subtract to Simplify:
 (3 - 4x) + (4x + 7)

• 4

• 8x + 10

• 0x + 4

• 10
