x+y=3,2x+5y=15,2x+2y=-3

x + y = 3, 2 x + 5 y = 15, 2 x + 2 y = - 3

No Solution

Solution steps

x + y = 3 2 x + 5 y = 15 2 x + 2 y = - 3

Isolate

x

for

x + y = 3 : x = 3 - y

Substitute

x = 3 - y

[2 (3 - y) + 5 y = 15 2 (3 - y) + 2 y = - 3]

Simplify

[6 + 3 y = 15 6 = - 3]

6 = - 3

is false, therefore the system of equations has no solution

No Solution

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

2 x - y = 0, y - x = 2

x + 8 y - 3 z = 7, - x + 3 y - 2 z = 1, 3 x + 2 y + z = 5

4 x + y = 0, x + 5 y = - 19

x + y + z - 2 = 6, x - 4 y + 5 z - 31 = 0
