Solve for a:

9+2a = -3-4a

• a=5

• a= -1

• a= -2

• a=2

What is the next step you should take?

1 + 4n = 10 - 14n

• Collect the variables (letters) to the left

• add 1 from both sides

• subtract 14n to both sides

• 1.5

• 6

• -6

• -1.5

• x=-10

• x=2

• No Solution

• All Real Numbers

4(2a + 3) = −3(a − 1) + 31

• a = 4

• a = -2

• a = -4

• a = 2

What is the first step to solve this equation:

-11 - 3x = 44 - 2x

• Add 3 to both sides

• Get the variable on one side

• Add 11 to both sides

• Add 2 on both sides.

Solve: -2x + 18 = 2x + 40

• x = -5.5

• x = 6.5

• x = -4.5

• x = 5.5
