Solve the equation and show all work. 4|x + 1/3| = 20
i'm kind of stuck hhh

Absolute value is a function that takes some number and outputs the size of that number, regardless of the sign. By definition, if , and if .

For example,

What this means for this problem is that there are two cases to consider:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

practice. practice. practice.
