When we solve a linear equation, we are trying to...

Guess what the variable is.

Use inverse operations (undoing) to isolate the variable.

Eliminate the variable.

How would you solve the equation below?

Multiply both sides of the equal sign by 4.

Subtract 4 from both sides of the equal sign.

How would you solve the equation?

Add 2x and 6 to get 8x, then divide by 8

Divide both sides by 2, then subtract 6 from both sides

Subtract 6 from both sides, then divide both sides by 2

Add 6 and 16 to get 22, then divide by 2

None of these.

If you did not get the first four questions correct, watch the first 5 and a half minutes of the video. You can watch further if you are really comfortable with solving equations, but for most of you, that will be far enough.
