Question

8x - 24 = y-3
9x + 9 = 2y + 2​

Answer 1

Explicación paso a paso:

{8x - 24 = y - 3

{9x + 9 = 2y + 2

{y = -21 + 8x

{9x + 9 = 2y + 2

9x + 9 = 2(-21 + 8x) + 2

9x + 9 = -42 + 16x + 2

9x + 9 = -40 + 16x

9x - 16x + 9 = -40

9x - 16x = -40 - 9

-7x = -40 - 9

-7x = -49

x = 7

y = -21 + 8 × 7

y = -21 + 56

y = 35

(x, y) = (7, 35)
