x+y=-7,3x-5y=11

Solution

x + y = - 7, 3 x - 5 y = 11

Solution

x = - 3, y = - 4

Solution steps

[x + y = - 7 3 x - 5 y = 11]

Isolate

x

for

x + y = - 7 : x = - 7 - y

Substitute

x = - 7 - y

[3 (- 7 - y) - 5 y = 11]

Simplify

[- 21 - 8 y = 11]

Isolate

y

for

- 21 - 8 y = 11 : y = - 4

For

x = - 7 - y

Substitute

y = - 4

x = - 7 - (- 4)

Simplify

x = - 3

The solutions to the system of equations are:

x = - 3, y = - 4

3x+7y=5,2x-4y=-9

3 x + 7 y = 5, 2 x - 4 y = - 9

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

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

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

x+5y=15,2x-3y=1

x + 5 y = 15, 2 x - 3 y = 1

x/2-y/5 =4, x/7+y/(15)=3

\frac{x}{2} - \frac{y}{5} = 4, \frac{x}{7} + \frac{y}{15} = 3
