Answer:

-5x+8y-7x-8y=-96

-12x =-96

X= 8

if X=8,

(-5×8)+8y=0

8y=40

y=5

x=8

y=5

The given equations are : -

−5x + 8y = 0 - [1]

-7x - 8y = -96 -[2]

Add the equations :

  • [tex]\mathrm{- 5x + 8y + (- 7x - 8y) = 0 + (- 96)}[/tex]

  • [tex]\mathrm{- 5x + 8y - 7x - 8y = - 96}[/tex]

  • [tex] - 12x = - 96[/tex]

  • [tex]x = 8[/tex]

_____________________________

plugging value of x in [1] :

  • [tex] - 5x + 8y = 0[/tex]

  • [tex]( - 5 \times 8) + 8y = 0[/tex]

  • [tex] - 40 + 8y = 0[/tex]

  • [tex]8y = 40[/tex]

  • [tex]y = 5[/tex]
