Answer:
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.
