x-7y=-11,5x+2y=-18

Solution

x - 7 y = - 11, 5 x + 2 y = - 18

Solution

x = - 4, y = 1

Solution steps

[x - 7 y = - 11 5 x + 2 y = - 18]

Isolate

x

for

x - 7 y = - 11 : x = - 11 + 7 y

Substitute

x = - 11 + 7 y

[5 (- 11 + 7 y) + 2 y = - 18]

Simplify

[- 55 + 37 y = - 18]

Isolate

y

for

- 55 + 37 y = - 18 : y = 1

For

x = - 11 + 7 y

Substitute

y = 1

x = - 11 + 7 \cdot 1

Simplify

x = - 4

The solutions to the system of equations are:

x = - 4, y = 1

- 10 x - 9 y = 29, - 6 x + 18 y = - 6

7x+5y-3z=16,3x-5y+2z=-8,5x+3y-7z=0

7 x + 5 y - 3 z = 16, 3 x - 5 y + 2 z = - 8, 5 x + 3 y - 7 z = 0

9x+6y=8,4x-2y=4

9 x + 6 y = 8, 4 x - 2 y = 4

x+y=g(x,y),8x-y=0

x + y = g (x, y), 8 x - y = 0

8x+4y=-4,10x-4y=4

8 x + 4 y = - 4, 10 x - 4 y = 4
