m+2n=4,3n-m=16

Solution

m + 2 n = 4, 3 n - m = 16

Solution

m = - 4, n = 4

Solution steps

[m + 2 n = 4 3 n - m = 16]

Isolate

m

for

m + 2 n = 4 : m = 4 - 2 n

Substitute

m = 4 - 2 n

[3 n - (4 - 2 n) = 16]

Simplify

[5 n - 4 = 16]

Isolate

n

for

5 n - 4 = 16 : n = 4

For

m = 4 - 2 n

Substitute

n = 4

m = 4 - 2 \cdot 4

Simplify

m = - 4

The solutions to the system of equations are:

m = - 4, n = 4

x + 4 y = 3 x - 2, y = 5

0.5 x = 2, x = 0

2x+3y=4,4x-3y=8

2 x + 3 y = 4, 4 x - 3 y = 8

3 x + 4 y = 10, x - y = 1

3x+4y=8,((16-6x))/y =8

3 x + 4 y = 8, \frac{( 16 - 6 x )}{y} = 8
