2x-y=4,-6x+3y=18

2 x - y = 4, - 6 x + 3 y = 18

No Solution

Solution steps

[2 x - y = 4 - 6 x + 3 y = 18]

Isolate

x

for

2 x - y = 4 : x = \frac{4 + y}{2}

Substitute

x = \frac{4 + y}{2}

[- 6 \cdot \frac{4 + y}{2} + 3 y = 18]

Simplify

[- 12 = 18]

- 12 = 18

is false, therefore the system of equations has no solution

No Solution

(1) 2 x + 3 y = 1, 3 x - y = 7

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

3 x + y = 2, 3 x + 2 y = 7

(x - 7)^{2} = 3 y, x = 0

\frac{1}{7} x + \frac{1}{6} y = 3, \frac{1}{2} x - \frac{1}{3} y = 5
