Question

7x - 11y =10
3x - 2y = 5

Answer 1

3x = 5 + 2y

x = 2y + 5 / 3

reemplazando en la primer ecuacion:

7(2y + 5 / 3) - 11y = 10

(14y + 35)/3 - 11y = 10

(14y + 35 + 33y)/3 = 10

-19 y + 35 = 10 * 30

-19 y = 30 - 35

y = -5 / -19

y = 0.26

volviendo a x:

x = (2 * .26 + 5 ) / 3

x = 1.84
