x+2y=5,4x-y=2

Solution

x + 2 y = 5, 4 x - y = 2

Solution

x = 1, y = 2

Solution steps

[x + 2 y = 5 4 x - y = 2]

Isolate

x

for

x + 2 y = 5 : x = 5 - 2 y

Substitute

x = 5 - 2 y

[4 (5 - 2 y) - y = 2]

Simplify

[20 - 9 y = 2]

Isolate

y

for

20 - 9 y = 2 : y = 2

For

x = 5 - 2 y

Substitute

y = 2

x = 5 - 2 \cdot 2

Simplify

x = 1

The solutions to the system of equations are:

x = 1, y = 2

3 x - 2 y = - 2, 5 x + 8 y = - 60

x-y+4z=5,2x+z=0,x+3y+z=-15

x - y + 4 z = 5, 2 x + z = 0, x + 3 y + z = - 15
