Question

Q.Write the given statements as linear equations in two variables.
i)The cost of a notebook is Rs.5 less than twice the cost of a pen.
ii)The cost of a table is Rs.100 more than half the cost of a chair.​

Answer 1

Answer:

1)X-2Y+5=0

2)X-Y/2-100=0

Step-by-step explanation:

1) let the cost of a notebook be X

let the cost of a pen be Y

X = 2Y-5

X-2Y+5=0

2)let the cost of a table be X

let the cost of a chair be Y

X=Y/2+100

X-Y/2-100=0
