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

Solution

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

Solution

x = 3, y = - 6

Solution steps

[2 x - y = 12 3 x + y = 3]

Isolate

x

for

2 x - y = 12 : x = \frac{12 + y}{2}

Substitute

x = \frac{12 + y}{2}

[3 \cdot \frac{12 + y}{2} + y = 3]

Simplify

[\frac{36 + 5 y}{2} = 3]

Isolate

y

for

\frac{36 + 5 y}{2} = 3 : y = - 6

For

x = \frac{12 + y}{2}

Substitute

y = - 6

x = \frac{12 - 6}{2}

\frac{12 - 6}{2} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = - 6
