Question

neha went to a sale to purchase some pants and skirts . when her friend asked her how many of each she had bought, she answered " the number of skirts are two less than twice the pants purchased. also the number of skirts is four less than four times the number of pants purchased ".​

Answer 1

Step-by-step explanation:

Let's the no. of pants consider as X

now no of skirts are two less than twice the pants purchased=2x -2

And also the number of skirts is four less than four times the number of pants purchased .=4-4x

then both are equal =2x-2=4-4x

solve this equation you will get answer.

let's solve it.

2x-2=4-4x

+4x+2x=4+2

6x=6

X=1

This means value of X is 1

and skirts are 2x-2 = 2×1 -2

2-2=0.

Answer 2

Answer:

x=1, y=0

Step-by-step explanation:

Let the number of pants purchased by Neha be 'x'

And number of skirts purchased be 'y'

From the given condition,

y = 2x - 2 ----------- (1)

y = 4x - 4 ----------- (2)

For equation (1):

x y = 2x - 2 (x,y)

2 2 (2,2)

3 4 (3,4)

For equation (2):

x y = 4x - 4 (x,y)

0 -4 (0,-4)

2 4 (2,4)

Points on the line represented by equation (1) are (2,2) and (3,4)

Points on the line represented by equation (2) are (0,-4) & (2,4)

Now, the points representing on graph is shown above

From the graph, we observed that:

• Two lines are intersecting at (1,0)

• Solutions of the equations is x = 1, y = 0

Therefore, Number of pants purchased by Neha is x = 1

And number of skirts purchased is y = 0
