Hey! Hope that I can help!
To do this, all we need to do is find 2 integers that can add up to be -20, or

+ [tex]x[tex] = -20. So, to get 2 integers that can add up to a specific value, an easy thing to do is to figure out what could add up to -20. One pair of numbers that would work here is
-5 and -15.
If this helped, please mark this answer the brainliest. Thanks!
Answer:
The jar of chermical contains 66g of Zinc.
Step-by-step explanation:
The ratio of Zinc to Copper is 3 : 13
A jar of the chemical contains 286g of copper.
Let the mass of the Zinc be xg.
= 
x =
= 66g
So the jar of chemical contains 66g of Zinc.
It's -18.
-1/6b=3
Multiply the reciprocal of -1/6 to both sides, this will get x by itself
(-6/1)*-1/6b=3*(-6/1)
b= -18/1
b= -18
