how to solve inequalities
Thank you for your program. Please solve the inequality -14>-a+4-5a and graph its solution if it is a real number.
Karin from Algebra Class says:
You are solving this inequality for a. We need to get a by itself. If you are more comfortable with a on the left hand side, then you can switch sides, but you must reverse the sign. It would look like this:
-a +4 - 5a < -14
Now you can start by combining like terms on the left: (-a - 5a = -6)
-6a +4 > -14
Now we need to get rid of the 4 by subtracting 4 from both sides:
-6a +4 -4 > -14 - 4
-6a > -18
Now divide by -6 on both sides:
-6a/-6 > -18 / -6
a > 3
Our final answer is a >3. On a number line, you would have an open circle on 3 with an arrow pointing to the right.
