x+y=8,2x-y=12

Solution

x + y = 8, 2 x - y = 12

Solution

x = \frac{20}{3}, y = \frac{4}{3}

Solution steps

[x + y = 8 2 x - y = 12]

Isolate

x

for

x + y = 8 : x = 8 - y

Substitute

x = 8 - y

[2 (8 - y) - y = 12]

Simplify

[16 - 3 y = 12]

Isolate

y

for

16 - 3 y = 12 : y = \frac{4}{3}

For

x = 8 - y

Substitute

y = \frac{4}{3}

x = 8 - \frac{4}{3}

8 - \frac{4}{3} = \frac{20}{3}

x = \frac{20}{3}

The solutions to the system of equations are:

x = \frac{20}{3}, y = \frac{4}{3}

4 x + 3 y = 8, 8 x - 9 y = - 77

x/(100)+8y=17,3x-200y=3800

\frac{x}{100} + 8 y = 17, 3 x - 200 y = 3800
