-x+4y=11,2x+y=-4

Solution

- x + 4 y = 11, 2 x + y = - 4

Solution

x = - 3, y = 2

Solution steps

[- x + 4 y = 11 2 x + y = - 4]

Isolate

x

for

- x + 4 y = 11 : x = - 11 + 4 y

Substitute

x = - 11 + 4 y

[2 (- 11 + 4 y) + y = - 4]

Simplify

[- 22 + 9 y = - 4]

Isolate

y

for

- 22 + 9 y = - 4 : y = 2

For

x = - 11 + 4 y

Substitute

y = 2

x = - 11 + 4 \cdot 2

Simplify

x = - 3

The solutions to the system of equations are:

x = - 3, y = 2

Popular Examples

x/2+y/3 =2, x/3+y/9 =1

\frac{x}{2} + \frac{y}{3} = 2, \frac{x}{3} + \frac{y}{9} = 1

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

b = - \frac{23}{3}, a = 0

x + y = 1, 1 x - y = - 1

5x+3y=41,2x+3y=20

5 x + 3 y = 41, 2 x + 3 y = 20
