x+y=-4,-x+2y=13

Solution

x + y = - 4, - x + 2 y = 13

Solution

x = - 7, y = 3

Solution steps

[x + y = - 4 - x + 2 y = 13]

Isolate

x

for

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

Substitute

x = - 4 - y

[- (- 4 - y) + 2 y = 13]

Simplify

[4 + 3 y = 13]

Isolate

y

for

4 + 3 y = 13 : y = 3

For

x = - 4 - y

Substitute

y = 3

x = - 4 - 3

Simplify

x = - 7

The solutions to the system of equations are:

x = - 7, y = 3

Popular Examples

x - y = 28, x - 3 y = 10

2x-y=4,-10x+5y=0

2 x - y = 4, - 10 x + 5 y = 0

3 x + y = 5, 2 x - y = 0

a = 6, b = 4, c = 7

(6)2x-2y=y,4x+3y=-2

(6) 2 x - 2 y = y, 4 x + 3 y = - 2
