Okay, take for example:
1+2=3 is the same as 1=3-2
See how we changed the place of the 2. We can do that as long we change + to - and vica versa.
Let's see your example:
6+y=-8
We move the 6 on the other side of the expression with the opposite sign (it is a rule) and we get:
y=-8-6
y=-14
The answer to your question is
86+y=99
y=99-86
y=13
Answer:
First you need to find what x is equal to.
Step-by-step explanation:
Since 3x-5 is what you need to find divide 3 by 3x to get x alone and do the same for -5/ 3 which -1.6666667, and you can estimate it to be -1.67 so x is about -1.67.

Answer:
0.87
Step-by-step explanation:
0.8/4=0.2
0.7-0.81=-0.11
3*-0.11=-0.33
