3x+y+1=0,2x-3y+8=0

Solution

3 x + y + 1 = 0, 2 x - 3 y + 8 = 0

Solution

x = - 1, y = 2

Solution steps

[3 x + y + 1 = 0 2 x - 3 y + 8 = 0]

Isolate

x

for

3 x + y + 1 = 0 : x = \frac{- y - 1}{3}

Substitute

x = \frac{- y - 1}{3}

[2 \cdot \frac{- y - 1}{3} - 3 y + 8 = 0]

Simplify

[\frac{- 11 y - 2}{3} + 8 = 0]

Isolate

y

for

\frac{- 11 y - 2}{3} + 8 = 0 : y = 2

For

x = \frac{- y - 1}{3}

Substitute

y = 2

x = \frac{- 2 - 1}{3}

\frac{- 2 - 1}{3} = - 1

x = - 1

The solutions to the system of equations are:

x = - 1, y = 2
