Question

by elimination method​

Answer 1

Answer:

2divided by 1300=650

2divided by 1400=700

Answer 2

Answer:

let the cost of pant be x and cost of shirt be y

Step-by-step explanation:

According to the question

3x+2y=1300....1and 2x+4y=1400..2

solve this equation by elimination method

3 +2y=1300(multiply this with 2)

2x+4y=1400(multiply this with 3)

6x+4y=2600

6x+12y=4200

change the sign into -- sign

-8y=-1600

y=1600/8=200

put y=200 in equation 1

3x+2y=1300

3x+2(200)=1300

3×+400=1300

3×=1300-400

3×=900

×=900/3=300

therefore cost of the pant is 300 and cost of the shirt is 200
