Answer:
-(20+z)/y = x
Step-by-step explanation:
-20=xy +z
Subtract z from each side
-20 -z = xy+z-z
-20 -z = xy
Divide each side by y
(-20 -z)/y = xy/y
Factor out a negative
-(20+z)/y = x
Answer:
its no solutions
Step-by-step explanation:
because u solve the 1st varibles in one of the equations,then subsitute the results into the other equations
Hmm, I think your answer would be 3x ≥ -6
