Answer:
See method below.
Step-by-step explanation:
m/n + n/3 = 2
2/m + n = 4
First eliminate the fractions by multiplying the first equation by 3n:-
3m + n^2 = 6n...........(1)
and the second equation by m:-
2 + mn = 4m..............(2)
Now we solve using substitution:-
From equation (2):-
4m - mn = 2
m = 2 / (4 - n)
Now substitute for m in equation (1):-
6/ (4 - n) + n^2 = 6n
6 + n^2(4 - n) = 6n(4 - n)
6 + 4n^2 - n^3 = 24n - 6n^2
n^3 - 10n^2 + 24n - 6 = 0
This will not factor so we could solve this using graphical software.
To find the values of the variable m we substitute the found values of n into one of the original equations and solve for m.
Answer:
y = - 10
Explanation:
Solve for y by simplifying both sides of the equation, then isolating the variable.
Answer:
1) x > 3,2
2) x < -0,7
Step-by-step explanation:
5x - 4 > 12
5x > 12 + 4
5x > 16
x > 16/5
x > 3,2
OR
12x + 5 < -4
12x < -4 - 5
13x < -9
x < -9/13
x < -0,7
