Answer:

Step-by-step explanation:

1) Number of Jeans = x

Number of blouses  = y

total items = 6

x + y = 6 ---------------------(I)

Cost of 'x' Jeans = 300 * x = 300x

Cost of 'y' blouses = 100 * y = 100y

300x + 100y = 1000 -------------------(II)

Equations:

x  + y = 6

300x + 100y = 1000

2)              Multiply equation (I) by (-100) and so y will be eliminated. Then, we could find the value of 'x'

(I)* (-100)              -100x - 100y = -600

(II)                          300x + 100y = 1000           {Now, add}

                             200x            = 400

x = 400/200

x = 2

Plug in x = 2 in equation(I)

 2 + y = 6

       y = 6 - 2

y = 4

Number of Jeans = 2

Number of blouses  = 4

3) The equation has one solution. so, they are consistent and independent.
