x+5y=-21,5x+3y+17=0,-2x+3y=3,4x+y+15=0

x + 5 y = - 21, 5 x + 3 y + 17 = 0, - 2 x + 3 y = 3, 4 x + y + 15 = 0

No Solution

Solution steps

x + 5 y = - 21 5 x + 3 y + 17 = 0 - 2 x + 3 y = 3 4 x + y + 15 = 0

Isolate

x

for

x + 5 y = - 21 : x = - 21 - 5 y

Substitute

x = - 21 - 5 y

5 (- 21 - 5 y) + 3 y + 17 = 0 - 2 (- 21 - 5 y) + 3 y = 3 4 (- 21 - 5 y) + y + 15 = 0

Simplify

- 22 y - 88 = 0 42 + 13 y = 3 - 19 y - 69 = 0

Isolate

y

for

- 22 y - 88 = 0 : y = - 4

Substitute

y = - 4

[42 + 13 (- 4) = 3 - 19 (- 4) - 69 = 0]

Simplify

[- 10 = 3 7 = 0]

7 = 0

is false, therefore the system of equations has no solution

No Solution

x^{3} + 8 x^{2} + 19 x + 12 = 0, x = - 4

6 x - 3 y = - 1, 3 x + 5 y - 8 = 0

x + 2 y - 4 = 2, x + 4 y - 6 = 0

3 x - 5 y = 20, 6 x - 10 y = - 40

y = \frac{1}{x ^{2}} - x, x = 2, x = 3
