Algebra: Linear Equations and Inequalities Review

Intermediate Algebra: Review of Linear Equations and Inequalities.

There is a typo on the (last) problem 6: |7x-4|=10,

Solving 7x-4=10 implies 7x=14, and hence 7x/7=14/7.
We get x=2 (instead of 7 as in the video), replace 7 by 2 for the rest of the problem.
