Answer:

{x,y}={-2,4}d

Step-by-step explanation:

Solve equation [2] for the variable  y

 [2]    y = -2x

// Plug this in for variable  y  in equation [1]

  [1]    8x - 3•(-2x) = -28

  [1]    14x = -28

// Solve equation [1] for the variable  x

  [1]    14x = - 28

  [1]    x = - 2

// By now we know this much :

   x = -2

   y = -2x

// Use the  x  value to solve for  y

   y = -2(-2) = 4

Anna007 [38]

Answer:

The dividend is 360, divisor is 6 and quotient is 60.

Step-by-step explanation:

Factors of 3= 3*1

Factors of 18= 3*2*3

Factors of 60= 3*2*2*5

Taking LCM= 3*2*2*2*3*5= 360

60 is a factor of 360

The dividend is 360

If 360 is divided by 6 we get 60 which is a multiple of 3

and 6 is a factor of 18.

Therefore the dividend is 360 divisor is 6 and quotient is 60.
