Question

determine o valor de x e y

 

  2x     3y     =       x      2y

  3       4             +1     y+4

Answer 1

2x     3y     =       x      2y 
3       4             +1     y+4

2x = x  ==> 2x-x = 0 ==> x = 0
3y=2y==> 2y-y = 0 ==> y = 0
x+1 = 3==> x = 3-1 ==>x =2
y+4 = 4==> y = 4-4 ==>y =0
