Question

favor n me deixe no vacuo
x/3+y/2=11/3 x+y=8

Answer 1

x/3+y/2=11/3

MMC (2,3) = 6

(2x + 3y)/6 = 2.11/6

2x + 3y = 11

x+y=8

2x + 3y = 11

x + y = 8 (-2)

2x + 3y = 11

- 2x - 2y = - 16 (+)

---------------------------

y = - 5

x + y = 8

x - 5 = 8

x = 8+5

x = 13

R.: X = 13; y = - 5
