Answer:
x = -3
Step-by-step explanation:
First Subtract the lowest variable which would be "y" from 9y. 9y changes to 8y and y cancels out, bring everything else down. the equation is now 8y-1=-25. Now add positive one to both sides -25 becomes -24 and -1 cancels out. the equation is now 8y=-24. -24 divided by 8 equals -3 and the 8y cancels out. the equation is now x equals -3.

Answer: Using context clues
Step-by-step explanation:
To get r you have to divide:
-8r=64
----------
-8
You would divide by -8 because you are trying to get r by itself and make sure when you divide one side divide the other one:
-8r=64
---------- r= -8
-8
You would get -8 when you divide 64/-8 because a negative and a negative gives you a positive hope this helps a bunch :)))))
