A=xy+yz
A=y*(x+z)
y=A/(x+z)
Yeah, mostly is has to be negative, but in some cases a is greater than 1 than we do some other operations.

Answer:
5p+s
Step-by-step explanation:
five friends jumping for one hour
-5x/6 + 1=7/18
lowest common multiple=18
-15x+18=7
-15x=7-18
-15x=-11
x=-11/-15=11/15
The solution set is [11/15]
we check it out.
-5(11/15) /6 + 1 =7/18
(-55/15) / 6 +1=7/18
-55/90 + 1=7/18
(-55+90) /90=7/18
35/90=7/18
7/18=7/18
