-x+3y=-5,2x-5y=9

Solution

- x + 3 y = - 5, 2 x - 5 y = 9

Solution

x = 2, y = - 1

Solution steps

[- x + 3 y = - 5 2 x - 5 y = 9]

Isolate

x

for

- x + 3 y = - 5 : x = 5 + 3 y

Substitute

x = 5 + 3 y

[2 (5 + 3 y) - 5 y = 9]

Simplify

[10 + y = 9]

Isolate

y

for

10 + y = 9 : y = - 1

For

x = 5 + 3 y

Substitute

y = - 1

x = 5 + 3 (- 1)

5 + 3 (- 1) = 2

x = 2

The solutions to the system of equations are:

x = 2, y = - 1

Popular Examples

(0.6)/x+2/y =5, 8/x-1/y =3

\frac{0.6}{x} + \frac{2}{y} = 5, \frac{8}{x} - \frac{1}{y} = 3

5x-3y=2,1x-2y=-1

5 x - 3 y = 2, 1 x - 2 y = - 1

74x-3y=8,6x-y-29/3 =0

74 x - 3 y = 8, 6 x - y - \frac{29}{3} = 0

3 x + 2 y = 6, 2 x + 3 = 4

2x+3y=10,-x+y=-5

2 x + 3 y = 10, - x + y = - 5
