x-2y=4,x-2y=0,x+y=4,x+y=1

x - 2 y = 4, x - 2 y = 0, x + y = 4, x + y = 1

No Solution

Solution steps

x - 2 y = 4 x - 2 y = 0 x + y = 4 x + y = 1

Isolate

x

for

x - 2 y = 4 : x = 4 + 2 y

Substitute

x = 4 + 2 y

4 + 2 y - 2 y = 0 4 + 2 y + y = 4 4 + 2 y + y = 1

Simplify

4 = 0 4 + 3 y = 4 4 + 3 y = 1

4 = 0

is false, therefore the system of equations has no solution

No Solution

4 x + y = 3, 4 x + 4 y = 16

x = 5 y + 8, - 7 x + 8 y = 25

5 x + 6 y = 12, 3 x + 5 y = 21

2 x + 3 y = 4, - 3 x + 2 y = 1

\frac{2}{x} + \frac{3}{y} = \frac{9}{( x y )}, \frac{4}{x} + \frac{9}{y} = \frac{21}{( x y )}
