x+3y=1,x-3y=7

Solution

x + 3 y = 1, x - 3 y = 7

Solution

x = 4, y = - 1

Solution steps

[x + 3 y = 1 x - 3 y = 7]

Isolate

x

for

x + 3 y = 1 : x = 1 - 3 y

Substitute

x = 1 - 3 y

[1 - 3 y - 3 y = 7]

Simplify

[1 - 6 y = 7]

Isolate

y

for

1 - 6 y = 7 : y = - 1

For

x = 1 - 3 y

Substitute

y = - 1

x = 1 - 3 (- 1)

1 - 3 (- 1) = 4

x = 4

The solutions to the system of equations are:

x = 4, y = - 1

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

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

5 x - y = 6, 5 x + 2 y = 2

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

23x+29y=98,29x-23y=110

23 x + 29 y = 98, 29 x - 23 y = 110

2x+3y+5=0,3x-2y-12=0

2 x + 3 y + 5 = 0, 3 x - 2 y - 12 = 0
