-2x+y=-4,2x-3y=8

Solution

- 2 x + y = - 4, 2 x - 3 y = 8

Solution

x = 1, y = - 2

Solution steps

[- 2 x + y = - 4 2 x - 3 y = 8]

Isolate

x

for

- 2 x + y = - 4 : x = - \frac{- 4 - y}{2}

Substitute

x = - \frac{- 4 - y}{2}

[2 (- \frac{- 4 - y}{2}) - 3 y = 8]

Simplify

[4 - 2 y = 8]

Isolate

y

for

4 - 2 y = 8 : y = - 2

For

x = - \frac{- 4 - y}{2}

Substitute

y = - 2

x = - \frac{- 4 - ( - 2 )}{2}

- \frac{- 4 - ( - 2 )}{2} = 1

x = 1

The solutions to the system of equations are:

x = 1, y = - 2

Popular Examples

x+16-3x+8y=23,y=4

x + 16 - 3 x + 8 y = 23, y = 4

5x-21=8y,-5y+10x=15

5 x - 21 = 8 y, - 5 y + 10 x = 15

x-5y=11,2x+34=0

x - 5 y = 11, 2 x + 34 = 0

16x-49y=25,2x-33y=12

16 x - 49 y = 25, 2 x - 33 y = 12

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