1/3x-1/3y=-1/3 ,-1/7x+1/8y= 2/7

\frac{1}{3} \cdot x - \frac{1}{3} \cdot y = - \frac{1}{3}, - \frac{1}{7} \cdot x + \frac{1}{8} \cdot y = \frac{2}{7}

x = - 9, y = - 8

Solution steps

[\frac{1}{3} x - \frac{1}{3} y = - \frac{1}{3} - \frac{1}{7} x + \frac{1}{8} y = \frac{2}{7}]

Isolate

x

for

\frac{1}{3} \cdot x - \frac{1}{3} \cdot y = - \frac{1}{3} : x = - 1 + y

Substitute

x = - 1 + y

[- \frac{1}{7} (- 1 + y) + \frac{1}{8} y = \frac{2}{7}]

Simplify

[\frac{8 - y}{56} = \frac{2}{7}]

Isolate

y

for

\frac{8 - y}{56} = \frac{2}{7} : y = - 8

For

x = - 1 + y

Substitute

y = - 8

x = - 1 - 8

Simplify

x = - 9

The solutions to the system of equations are:

x = - 9, y = - 8

x + y - 2 z = 8, 2 x - y + z = 3, 3 x + y + 2 z = 6

- m + n = - 1, 4 m - 2 n = 5

4 (x - y) = - 2, 3 x - 7 y = - 25 - 2 (x + y)

x - y = 3, 2 x + 4 y = 12

x + y = 2, 4 - 3 x + y = 0
