3x+2y=-9,5x-y=-2

Solution

3 x + 2 y = - 9, 5 x - y = - 2

Solution

x = - 1, y = - 3

Solution steps

[3 x + 2 y = - 9 5 x - y = - 2]

Isolate

x

for

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

Substitute

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

[5 \cdot \frac{- 9 - 2 y}{3} - y = - 2]

Simplify

[\frac{- 45 - 13 y}{3} = - 2]

Isolate

y

for

\frac{- 45 - 13 y}{3} = - 2 : y = - 3

For

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

Substitute

y = - 3

x = \frac{- 9 - 2 ( - 3 )}{3}

\frac{- 9 - 2 ( - 3 )}{3} = - 1

x = - 1

The solutions to the system of equations are:

x = - 1, y = - 3

Popular Examples

((3x))/2-((5y))/3 =-2, x/3+y/2 = 13/6

\frac{( 3 x )}{2} - \frac{( 5 y )}{3} = - 2, \frac{x}{3} + \frac{y}{2} = \frac{13}{6}

7 x - 4 y = 9, 4 y = 15

3x+2y=8,5x-3y=7

3 x + 2 y = 8, 5 x - 3 y = 7

y-4x=-42,((2x))/9+((5y))/6 =-3

y - 4 x = - 42, \frac{( 2 x )}{9} + \frac{( 5 y )}{6} = - 3

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