Question

alguem resolve esse sistema por favor com urgencia para hj a noite x/2+y/3=6 2x+y=15

Answer 1

x/2 + y/ 6

2x + y = 15  →  2x = 15 + y  →  x = 15 - y / 2

( 15 - y/2 / 2 ) + y/3 = 6

( 15- y / 2  . 1/2 ) + y/3 = 6

15 - y/4 + y/3 = 6

45 - 3y + 4y = 72

y = 72 - 45

y = 27

x = 15 - y/2

x = 15 - 27/2

x = - 12/2

x = - 6
