We start with:
-10 = xy + z
When you want to solve for a certain variable, you generally follow pemdas in reverse, so subtract z from both sides first:
-10 - z = xy
And finally, divide both sides by y:
(-10 - z)/y = x
and there we go! sorry for the badly typed equations, I'm on my phone so there's only so much a can do :( hope I helped, and let me know if you have any questions!
Answer:
because thats the answer (; your welcome
Step-by-step explanation:
Answer:
$45 (corrected answer)
Step-by-step explanation:
Given
Gavin : Jim = 1 : 3
fraction that Gavin gets = 1 / (1+3) = 1/4
fraction that Jim gets = 3 / (1+3) = 3/4
given that Gavin gets $15,
Gavin's share = (1/4) ----> equivalent to $15
Jim's share = (3/4) ----> equivalent to $15 x 3 = $45
One is making 15,000 and the other is making 13,000 so yeah hope this is what you were looking for ^ !
