9514 1404 393

  (x, y) = (-1/2, 3/4)

Step-by-step explanation:

A graphing calculator does a nice job of finding the solution.

  (x, y) = (-1/2, 3/4)

__

You can eliminate y by adding twice the second equation to the first.

  (2x +8y) +2(24x -4y) = (5) +2(-15)

  50x = -25

  x = -1/2 . . . . . . divide by 50

__

  24(-1/2) -4y = -15 . . . . .substitute for x in the second equation

  -4y = -3 . . . . . . . . . add 12

  y = 3/4 . . . . . . . . . divide by the coefficient of y

The solution is (x, y) = (-1/2, 3/4).

sorry no step by step

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
