x+y=3,x-2y=10

Solution

x + y = 3, x - 2 y = 10

Solution

x = \frac{16}{3}, y = - \frac{7}{3}

Solution steps

[x + y = 3 x - 2 y = 10]

Isolate

x

for

x + y = 3 : x = 3 - y

Substitute

x = 3 - y

[3 - y - 2 y = 10]

Simplify

[3 - 3 y = 10]

Isolate

y

for

3 - 3 y = 10 : y = - \frac{7}{3}

For

x = 3 - y

Substitute

y = - \frac{7}{3}

x = 3 - (- \frac{7}{3})

3 - (- \frac{7}{3}) = \frac{16}{3}

x = \frac{16}{3}

The solutions to the system of equations are:

x = \frac{16}{3}, y = - \frac{7}{3}
