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
