In your question you have two equations. They are...
m + n = 1000 Equation (1)
0.05 + 0.06n = 57 Equation (2)
It is a rule of thumb that if you have two equations and two unknowns (the unknowns in this case are "m" and "n") you can solve for them. Also remember if you have three euqations and three unknowns you can solve for them.. four euqations four unknowns... etc..
Ok first take the 2nd equation and solve for "n"
0.05 + 0.06n = 57
0.06n = 56.95
n= 949 and 1/6
Now that you have "n" you can put it into the 1st euqation and solve for "m"
m + (5695/6) = 1000
m = 50 and 5/6
Therefore you answers are...
n=949.16666 or 949 1/6 or 5695/6
m=50.83333 or 50 5/6 or 305/6
How do you solve 4y plus x equals 8
2000
1000 plus 10000 equals 11000
6000.......it's actually 5,100

100+1000=1100
No, it equals 1100.
All you need to do is substitute the given values of a and c into the equation, then solve for c: a2 + c2 = b2 102 + 302 = b2 100 + 900 = b2 b2 = 1000 b = √1000 b = 10√10
