Answer:
z=34
Step-by-step explanation:
2 + 8 - z = -24
add
10-z = -24
subtract 10 from each side
10-z-10 = -24-10
-z = -34
multiply by -1
-1*-z = -34 * -1
z = 34
Metimes we do not always need to give detailed answers to problems - we just want a rough idea. When we are faced with a long number, we could round it off to the nearest thousand, or nearest million. And when we get a long decimal answer on a calculator, we could round it off to a certain number of decimal places.<span>Another method of giving an approximated answer is to round off using significant figures.</span>
First off, you have to find a common denominator between 6 and 9 which is 18, so to rewrite your equation using the common denominators it would be 15/18+(-8/18)-(-36/18) when you combine these it equals (7/18)-(-36/18)=43/18
