Question

Resolver {3x/2 + 3y/4 +1/2 = -1
{ 6x - y/5 - 18/5 = 0

Answer 1

Respuesta:

1/2 y -3

Explicación paso a paso:

• 4.(3x/2 + 3y/4 +1/2) =4.( -1)= 6x + 3y +2 = -4 = 6x + 3y = -6

• 5.(6x - y/5 - 18/5 )= 5.(0)  = 3.(30x - y) = 3.(18)= 90x - 3y = 54

Se suman ambos

96x=48        x=1/2

reemplazando

6(1/2)+ 3y = -6           y=-3
