We have two numbers say a, b. And a system of equations.

It looks a bit intimidating but it's actually very easy.
Instead of term a + b in the second equation we can say it's zero because the first equation describes a + b as being equal to 0.
So,

The above equation is not true therefore numbers a and b do not exists in the real number domain.

No solution.
Hope this helps.
(61+36)460+5000M= 49620
(M equals operation cost per month)
18a +6 - 30 = 6a-4
12a -30 =-10
12a=20
a= 5/3
Answer:
i believe it would be $443.75
Step-by-step explanation:
just add 8.75 to 9.00 then multiply it by 25
8.75+9.00= 17.75 x 25= 443.75
if its a different type of equation then maybe this didn't help but i hope it does
