Solve

-19 = -8 (-4+a) - (2a+1)

• -1

• 14

• -5

• 5

Solve for x:
5x - 14 = 8x + 4

• x = 6
• x = -6
• x = -18/13
• x = 10/3

30 + 6t = 11t

• 3
• 5
• 6
• 30

What is the first step you should take to solve this problem?

-3(x - 2) = -8 +9b

• add 8 to both sides

• subtract 9b from both sides

• Distribute -3 to the x and -2

• add 2 to both sides

Check all steps that you would need to take to solve this equation:

 $4x+7-2x=18-3x$  

• Use distributive property to get rid of parentheses

• Combine like terms

• Move the variable to one side of the equation

• Use inverse operations to isolate and solve for the variable.

Solve for x:

4(1-x) + 3x = -2x - 2

• x= -6

• x= 3

• x= 6

• x= -3

Solve for x:

3 ( a + 22 ) = 12a + 30

• a = 8

• a = 2

• a = 4

• a = -2
