Here is your inequality:
You're looking for z. To do that, you need to remove everything on the same side of z. The only thing with z is positive . To remove it, you need to do the opposite of it, which is negative , which is the same as subtracting . Subtract:
Subtract from . Since they have a different denominator(bottom number in a fraction), change them into fractions with common denominator. To find a common denominator, list the multiples of both numbers and see what is common.
In the numbers listed above ↑, the only common multiples is 40. That means you need to change both fractions so that they both have a denominator of 40.
Here is your new equation:
Subtract:
Your answer is z >
