What is the FIRST step to solving the equation |x + 1| = 4?

Back

Set up 2 equations: x + 1 = 4 and x + 1 = -4.

Front

When do you set up 2 equations in |x + 2| + 3 = 4?

Back

After you subtract 3 from both sides.

Front

What is the FIRST step to solve the equation -2|x + 3| = -10?

Back

Divide by -2 on both sides.

Front

What does |x| represent?

Back

The distance of x from 0 on the number line.

Front

How do you solve |x| = a where a > 0?

Back

Set up two equations: x = a and x = -a.
