Question

método de igualación 5x+2y=1
4x+3y=5​

Answer 1

Respuesta:

x = -1

y = 3

Explicación paso a paso:

5x + 2y = 1

4x + 3y = 5

2y = 1​ - 5x

y = (1 - 5x) / 2

4x + 3y = 5

3y = 5 - 4x

y = (5 - 4x) / 3

(1 - 5x) / 2 = (5 - 4x) / 3

3(1 - 5x) = 2(5 - 4x)

3 - 15x = 10 - 8x

-15x + 8x = 10 - 3

-7x = 7

x = 7 / -7

x = -1

y = (5 - 4x) / 3

y = (5 - 4(-1)) / 3

y = (5 + 4) / 3

y = 9 / 3

y = 3

4x + 3y = 5

4(-1) + 3(3) = 5

-4 + 9 = 5

5 = 5
