m+n=38,2m-4n=-8

Solution

m + n = 38, 2 m - 4 n = - 8

Solution

m = 24, n = 14

Solution steps

[m + n = 38 2 m - 4 n = - 8]

Isolate

m

for

m + n = 38 : m = 38 - n

Substitute

m = 38 - n

[2 (38 - n) - 4 n = - 8]

Simplify

[76 - 6 n = - 8]

Isolate

n

for

76 - 6 n = - 8 : n = 14

For

m = 38 - n

Substitute

n = 14

m = 38 - 14

Simplify

m = 24

The solutions to the system of equations are:

m = 24, n = 14

x+y=16,5x+2y=50

x + y = 16, 5 x + 2 y = 50

x + y = 20, x - y = 8

3x+y=-5,-5x+2y=-19

3 x + y = - 5, - 5 x + 2 y = - 19

x-y=4,x+y=30,r=30-x

x - y = 4, x + y = 30, r = 30 - x

(2)x+7y=10,3x-2y=7

(2) x + 7 y = 10, 3 x - 2 y = 7
