2x+5y=1,3x-2y=-8

Solution

2 x + 5 y = 1, 3 x - 2 y = - 8

Solution

x = - 2, y = 1

Solution steps

[2 x + 5 y = 1 3 x - 2 y = - 8]

Isolate

x

for

2 x + 5 y = 1 : x = \frac{1 - 5 y}{2}

Substitute

x = \frac{1 - 5 y}{2}

[3 \cdot \frac{1 - 5 y}{2} - 2 y = - 8]

Simplify

[\frac{3 - 19 y}{2} = - 8]

Isolate

y

for

\frac{3 - 19 y}{2} = - 8 : y = 1

For

x = \frac{1 - 5 y}{2}

Substitute

y = 1

x = \frac{1 - 5 \cdot 1}{2}

\frac{1 - 5 \cdot 1}{2} = - 2

x = - 2

The solutions to the system of equations are:

x = - 2, y = 1

7 x - 4 y = 1, 1 - 5 + 6 y = 0

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