2x-3y+9=0,x+2y=-1

Solution

2 x - 3 y + 9 = 0, x + 2 y = - 1

Solution

x = - 3, y = 1

Solution steps

[2 x - 3 y + 9 = 0 x + 2 y = - 1]

Isolate

x

for

2 x - 3 y + 9 = 0 : x = \frac{3 y - 9}{2}

Substitute

x = \frac{3 y - 9}{2}

[\frac{3 y - 9}{2} + 2 y = - 1]

Simplify

[\frac{7 y - 9}{2} = - 1]

Isolate

y

for

\frac{7 y - 9}{2} = - 1 : y = 1

For

x = \frac{3 y - 9}{2}

Substitute

y = 1

x = \frac{3 \cdot 1 - 9}{2}

\frac{3 \cdot 1 - 9}{2} = - 3

x = - 3

The solutions to the system of equations are:

x = - 3, y = 1

3x^2+2x-k=0,x= 1/3

3 x^{2} + 2 x - k = 0, x = \frac{1}{3}

x + y = 4, 5 x - 2 y = 3

x + 5 y = 11, 3 x - y = 1
