2x-y=2,4x-4y=6

Solution

2 x - y = 2, 4 x - 4 y = 6

Solution

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

Solution steps

[2 x - y = 2 4 x - 4 y = 6]

Isolate

x

for

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

Substitute

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

[4 \cdot \frac{2 + y}{2} - 4 y = 6]

Simplify

[- 2 y + 4 = 6]

Isolate

y

for

- 2 y + 4 = 6 : y = - 1

For

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

Substitute

y = - 1

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

Simplify

x = \frac{1}{2}

The solutions to the system of equations are:

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

x+y+z=1,6x-y+z=0,-9y+9z=-27

x + y + z = 1, 6 x - y + z = 0, - 9 y + 9 z = - 27

9a+5b=15,3a+2b=-6

9 a + 5 b = 15, 3 a + 2 b = - 6

-5x+6y=7,4x+3y=10

- 5 x + 6 y = 7, 4 x + 3 y = 10

x+3y=6,5x-2y=12

x + 3 y = 6, 5 x - 2 y = 12

3x-5y=1,2x+3y=7

3 x - 5 y = 1, 2 x + 3 y = 7
