x-y=4,x+3y=0

Solution

x - y = 4, x + 3 y = 0

Solution

x = 3, y = - 1

Solution steps

[x - y = 4 x + 3 y = 0]

Isolate

x

for

x - y = 4 : x = 4 + y

Substitute

x = 4 + y

[4 + y + 3 y = 0]

Simplify

[4 + 4 y = 0]

Isolate

y

for

4 + 4 y = 0 : y = - 1

For

x = 4 + y

Substitute

y = - 1

x = 4 - 1

Simplify

x = 3

The solutions to the system of equations are:

x = 3, y = - 1

3x+4y=-7,-3x-8y=-1

3 x + 4 y = - 7, - 3 x - 8 y = - 1

4x-y=20,7x+2y=18

4 x - y = 20, 7 x + 2 y = 18

x-2y=3,x+4y-20=0

x - 2 y = 3, x + 4 y - 20 = 0

1/7 x+1/6 y=3, 1/2 x+1/3 y=2

\frac{1}{7} x + \frac{1}{6} y = 3, \frac{1}{2} x + \frac{1}{3} y = 2

x+y=-4,-x+2y=13

x + y = - 4, - x + 2 y = 13
