m+n=1,2m-n=4

Solution

m + n = 1, 2 m - n = 4

Solution

m = \frac{5}{3}, n = - \frac{2}{3}

Solution steps

[m + n = 1 2 m - n = 4]

Isolate

m

for

m + n = 1 : m = 1 - n

Substitute

m = 1 - n

[2 (1 - n) - n = 4]

Simplify

[2 - 3 n = 4]

Isolate

n

for

2 - 3 n = 4 : n = - \frac{2}{3}

For

m = 1 - n

Substitute

n = - \frac{2}{3}

m = 1 - (- \frac{2}{3})

1 - (- \frac{2}{3}) = \frac{5}{3}

m = \frac{5}{3}

The solutions to the system of equations are:

m = \frac{5}{3}, n = - \frac{2}{3}
