Explanation:
When trying to solve an algebraic inequality for a variable, we can apply the same rules we use to solve an equation; however, we must maintain our inequality throughout the problem.
Our goal is to completely isolate
Simplify the left side by combining like terms (all terms containing
Subtract
Multiply both sides by
- If we were multiplying or dividing either side by a negative number, the sign would switch (I.E., become
#<=# ); however, this does not happen here. The prospect of this happening is why we must maintain our inequality all throughout the problem.
