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

Solution

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

Solution

x = - 4, y = - 2

Solution steps

[2 x + y = - 10 x - 3 y = 2]

Isolate

x

for

2 x + y = - 10 : x = \frac{- 10 - y}{2}

Substitute

x = \frac{- 10 - y}{2}

[\frac{- 10 - y}{2} - 3 y = 2]

Simplify

[\frac{- 10 - 7 y}{2} = 2]

Isolate

y

for

\frac{- 10 - 7 y}{2} = 2 : y = - 2

For

x = \frac{- 10 - y}{2}

Substitute

y = - 2

x = \frac{- 10 - ( - 2 )}{2}

\frac{- 10 - ( - 2 )}{2} = - 4

x = - 4

The solutions to the system of equations are:

x = - 4, y = - 2

Popular Examples

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

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

4x-4=10,5x+2y=14

4 x - 4 = 10, 5 x + 2 y = 14

x+y=13,70x+80y=980

x + y = 13, 70 x + 80 y = 980

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