5m+n = 37
m-2n = 14 => m = 2n+14
Substitute the value of m into the top equation:
5(2n+14)+n = 37
10n+70+n = 37
10n+n = 37-70
11n = -33
Divide both sides by 11 to find the value of n:
n = -3
Substitute the value of n into the original equations to find the value of m:
Therefore: n = -3 and m = 8

How do you solve 2x plus 2y equals 4 and 4x plus y equals 1?
2x + 2y = 44x + y = 1There are many methods you can use to solve this system of equations (graphing, elimination, substitution, matrices)...but no matter what method you use, you should get x = -1/3 and y = 7/3.
If Using substitution method to solve the equation y equals 8x plus 3 and y equals 7?
This is not Calculus.y=7(Already solved)substiute y=7 into y=8xtherefore 7 = 8xtherefore x = 7/8
Use the substitution method to solve the system of equations x plus 2y equals 12 and y equals x plus 3?
x+2(x+3) = 12 x+2x+6 = 12 x+2x = 12-6 3x = 6 x = 2 and y = 5

Solve using substitution x plus y equals 3 and y equals 9?
Since the second equation is already solved for "y", you can replace "y" by "9" in the other equation. Then solve the new equation for "x".
