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

Solution

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

Solution

x = - 1, y = 1

Solution steps

[5 x + 2 y = - 3 x + 5 y = 4]

Isolate

x

for

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

Substitute

x = \frac{- 3 - 2 y}{5}

[\frac{- 3 - 2 y}{5} + 5 y = 4]

Simplify

[\frac{- 3 + 23 y}{5} = 4]

Isolate

y

for

\frac{- 3 + 23 y}{5} = 4 : y = 1

For

x = \frac{- 3 - 2 y}{5}

Substitute

y = 1

x = \frac{- 3 - 2 \cdot 1}{5}

\frac{- 3 - 2 \cdot 1}{5} = - 1

x = - 1

The solutions to the system of equations are:

x = - 1, y = 1

Popular Examples

x + y = 6, x - y = 4

3 x - y = 3, 9 x - 3 y = 9

x-3y=1,3x-2y+4=0

x - 3 y = 1, 3 x - 2 y + 4 = 0

x + y = 10, - 2 x + y = 1

2x-3y=10,4x-y=10

2 x - 3 y = 10, 4 x - y = 10
