x+3y=1,3y=x+3

Solution

x + 3 y = 1, 3 y = x + 3

Solution

x = - 1, y = \frac{2}{3}

Solution steps

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

Isolate

x

for

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

Substitute

x = 1 - 3 y

[3 y = (1 - 3 y) + 3]

Simplify

[3 y = - 3 y + 4]

Isolate

y

for

3 y = - 3 y + 4 : y = \frac{2}{3}

For

x = 1 - 3 y

Substitute

y = \frac{2}{3}

x = 1 - 3 \cdot \frac{2}{3}

1 - 3 \cdot \frac{2}{3} = - 1

x = - 1

The solutions to the system of equations are:

x = - 1, y = \frac{2}{3}

3x+8y=19,4x-y=2

3 x + 8 y = 19, 4 x - y = 2

2x+4y+z=23,6x+2y-z=35,4x-y+2z=19

2 x + 4 y + z = 23, 6 x + 2 y - z = 35, 4 x - y + 2 z = 19

x - 3 y = 5, 7 x - 8 y = 6

5x+3y=35,2x+4y=28

5 x + 3 y = 35, 2 x + 4 y = 28

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

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