-4x= 12 divide both sides
x=-3
Well, by doing the work and trying to solve this equation, i have came to the terms that it is a no solution problem
3/5n - 4/5 = 1/5n....multiply everything by 5 to get rid of the fractions
3n - 4 = n
-4 = n - 3n
-4 = -2n
-4/-2 = n
2 = n <==
Answer:
x=0 y=0
Step-by-step explanation:
multiple the first equation by 2
after subtract equation 2 from 1
after getting x you substitute the value of x in any of the equation for your y
