x-y=9,2x-y=13

Solution

x - y = 9, 2 x - y = 13

Solution

x = 4, y = - 5

Solution steps

[x - y = 9 2 x - y = 13]

Isolate

x

for

x - y = 9 : x = 9 + y

Substitute

x = 9 + y

[2 (9 + y) - y = 13]

Simplify

[18 + y = 13]

Isolate

y

for

18 + y = 13 : y = - 5

For

x = 9 + y

Substitute

y = - 5

x = 9 - 5

Simplify

x = 4

The solutions to the system of equations are:

x = 4, y = - 5

Popular Examples

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

2x+3y=1,6x+5y=1

2 x + 3 y = 1, 6 x + 5 y = 1

-x^2x=0,y=6,y=1,y=5

- x^{2} x = 0, y = 6, y = 1, y = 5

2x+5y=3,(k+1)x+2(k+2)y=2k

2 x + 5 y = 3, (k + 1) x + 2 (k + 2) y = 2 k

3x-2y=-2,5x+8y=-60

3 x - 2 y = - 2, 5 x + 8 y = - 60
