2x+3y=9,(a+b)x+(2a-b)y=3(a+b+1)

2 x + 3 y = 9, (a + b) x + (2 a - b) y = 3 (a + b + 1)

No Solution

Solution steps

[2 x + 3 y = 9 (a + b) x + (2 a - b) y = 3 (a + b + 1)]

Isolate

x

for

2 x + 3 y = 9 : x = \frac{9 - 3 y}{2}

Plug the solutions

x = \frac{9 - 3 y}{2}

into

(a + b) x + (2 a - b) y = 3 (1 + a + b)

For

(a + b) x + (2 a - b) y = 3 (1 + a + b)

, subsitute

x

with

\frac{9 - 3 y}{2} : y = \frac{- 3 b - 3 a + 6}{a - 5 b}; a \neq = 5 b

Plug the solutions

y = \frac{- 3 b - 3 a + 6}{a - 5 b}

into

2 x + 3 y = 9

For

2 x + 3 y = 9

, subsitute

y

with

\frac{- 3 b - 3 a + 6}{a - 5 b} : x = \frac{9 ( a - 2 b - 1 )}{a - 5 b}

Verify solutions by plugging them into the original equations

No Solution

2 x + y = 2, x y x + 2 y = 4 x y

6 x^{2} - 40 x + 24 = 0, 6 y^{2} + 100 y - 34 = 0

x_{1} = \frac{( 5 )}{3}, x^{2} = \frac{( 5 )}{5}

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

x = 7 - 3 y, x^{2} - y^{2} = 39
