Answer:
The two variables are
Step-by-step explanation:
We have been mentioned here that two equations are to be solved. They are as follows:
5m-3n = 16 and m-6n = -7
Therefore we will multiply 1 with the first equation and 5 with the other one so as to make one of the variables in both equations equal:
1(5m-3n) = 1(16)
⇒ 5m - 3n = 16
5(m-6n) = (5) (-7)
⇒ 5m - 30n = -35
Now we subtract both these equations and get:
5m - 3n - (5m - 30n) = 16 - (-35)
⇒ 5m -3n -5m + 30n = 16 + 35
⇒ 27n = 51
⇒ n = 51 ÷ 27
⇒ n =
And therefore putting n we get m to be,
m - 6× = -7
⇒ m = -7 +
⇒ m =
Therefore the two variables are
