Question

If [-8 x] + [y -2] = [-3 2], then the value of x + y is:

Answer 1

Answer:

∴ x+y = 9

Step-by-step explanation:

given,

  [-8 x] + [y -2] = [-3 2]

then,

   [-8+y  x+ (-2)] = [ -3 2]

or, [ y-8   x-2] = [-3  2]

here,

   x-2 = 2

or, x = 2+2

∴ x = 4

again,

  y-8 = -3

or, y = -3 +8

∴ y = 5

now,

 ∴ x + y = 4+5

           = 9

Answer 2

Answer:

-8x+y-2=-32

8x+y+2=+32

8x+y=30

x+y=30/8

x+y=3.75
