Resposta:
(a) (3/2)y-(11/10) = 0
(b) (4/3)x-(17/9) = 0
Explicação passo-a-passo:
(a)
2y-(3/5) = (2/4)y+(1/2)
2y-(2/4)y-(3/5)-(1/2) = 0
(8/4)y-(2/4)y-(6/10)-(5/10) = 0
(6/4)y-(11/10) = 0
(3/2)y-(11/10) = 0
(b)
(5/3)x+(1/9) = (2/6)x-2
(5/3)x+(1/9) = (1/3)x-2
(5/3)-(1/3)x+(1/9)-2 = 0
(4/3)x+(1/9)-(18/9) = 0
(4/3)x-(17/9) = 0
