Question

Determine x e y de modo que:
(X-2,2y +3) = ( 3x-1,y +5)
URGENTE

Answer 1

Resposta:

x= -1/2

y=2

Explicação passo-a-passo:

x-2=3x-1

x-3x=-1+2

-2x=1

x= -1/2

2y +3=y +5

2y-y=5-3

y=2

Answer 2

a ) (x - 2,2y +3) = (3x- 1,y +5)

x - 2 = 3x- 1 ==> 3x - x = - 2 + 1 ==> 2x = - 1 ==> x = -1/2

2y + 3 = y+5 ==> 2y-y = 5-3 ==> y = 2

================================================

b ) (x,2x - y) = (y,3)

x = y ==> y = 3

2x - y = 3 ==> 2x - x = 3 ==> x = 3
