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

Solution

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

Solution

x = 0, y = - 3

Solution steps

[x = 2 y + 6 y = 2 x - 3]

Substitute

x = 2 y + 6

[y = 2 (2 y + 6) - 3]

Simplify

[y = 4 y + 9]

Isolate

y

for

y = 4 y + 9 : y = - 3

For

x = 2 y + 6

Substitute

y = - 3

x = 2 (- 3) + 6

2 (- 3) + 6 = 0

x = 0

The solutions to the system of equations are:

x = 0, y = - 3

5 x + 6 y = 20, 3 x + 8 y = 34

x+y-z+t=6,y+z=1,z+2t=6,2t=8

x + y - z + t = 6, y + z = 1, z + 2 t = 6, 2 t = 8
