2x+3y=7,(a-b)x+(a+b)y=3a+b-2

2 x + 3 y = 7, (a - b) x + (a + b) y = 3 a + b - 2

No Solution

Solution steps

[2 x + 3 y = 7 (a - b) x + (a + b) y = 3 a + b - 2]

Isolate

x

for

2 x + 3 y = 7 : x = \frac{7 - 3 y}{2}

Plug the solutions

x = \frac{7 - 3 y}{2}

into

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

For

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

, subsitute

x

with

\frac{7 - 3 y}{2} : y = \frac{9 b - a - 4}{- a + 5 b}; a \neq = 5 b

Plug the solutions

y = \frac{9 b - a - 4}{- a + 5 b}

into

2 x + 3 y = 7

For

2 x + 3 y = 7

, subsitute

y

with

\frac{9 b - a - 4}{- a + 5 b} : x = \frac{2 ( 2 b + 3 - a )}{- a + 5 b}

Verify solutions by plugging them into the original equations

No Solution

x^{2} + 2 y^{2} = 54, 2 x - y = - 9

x - 3 y = 3, - x + 3 y = - 3

5 c = 19 a, b = 1

x + y + z = 4, x + y - z = 6

5 x^{2} + 21 x - 11 y = 2 x - 1, y = 1
