2x-y=1,2x-3y=7

Solution

2 x - y = 1, 2 x - 3 y = 7

Solution

x = - 1, y = - 3

Solution steps

[2 x - y = 1 2 x - 3 y = 7]

Isolate

x

for

2 x - y = 1 : x = \frac{1 + y}{2}

Substitute

x = \frac{1 + y}{2}

[2 \cdot \frac{1 + y}{2} - 3 y = 7]

Simplify

[1 - 2 y = 7]

Isolate

y

for

1 - 2 y = 7 : y = - 3

For

x = \frac{1 + y}{2}

Substitute

y = - 3

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

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

x = - 1

The solutions to the system of equations are:

x = - 1, y = - 3

2x+y-3z=0,4x+2y-6z=0,x-y+z=0

2 x + y - 3 z = 0, 4 x + 2 y - 6 z = 0, x - y + z = 0

2x+3y=13,4x-y=-2

2 x + 3 y = 13, 4 x - y = - 2

7x-3y=10,3x-5y=-5

7 x - 3 y = 10, 3 x - 5 y = - 5

2 x + y = 10, x + y = 7

2x+7y=1,1x-3y=-3

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