One/Two Step Equations, Variables on Both Sides

7x = 4x + 33

• x = 3

• x = 11

• x = 21

• x = 88

• Combining  $-14x$  and  $3x$  to get  $-11x.$  

• Adding 7 to both sides of the equation.

• Subtracting 2 from both sides of the equation. 

Solve: -18 - 6x = 6(1 + 3x)

• -1

• 1

• No Solution

• Infinite Solutions

In order to solve an equation, we must get variables on side of an equation, and constants on the opposite side.

• True

• False

What operation did he perform to get from Step 1 to Step 2?

• Subtracted 2x from both sides of the equation

• Subtracted 9 from both sides of the equation

• Multiplied both sides of the equation by 3

• Added -3 to both sides of the equation

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

• subtract 8n to both sides

• multiply 6n to both sides

• combine the like terms 4n + -6n

• add 1 to both sides

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
