1. The cost of a notebook is twice the cost of a pen. Write a line
plebook is twice the cost of a pen. Write a linear equation in two
variables to represent this statement.
(Take the cost of a notebook to be x and that of a pen to be y).
2. Express the following linear equations in the form ax + by + c = 0 and indi
values of a, b and e in each case:
© 2x+3y = 9.35 (x-2-10-0 in) - 2x + 3y 6 () - 3y
(v) 2x= -5y (vi) 3x+2-0 (vii) y-2-0 (vi) 5 = 2x

Answer 1

Answer:

1st questions answer is x - 2y= 0

Explanation:

if we take the cost of notebook as x and cost of pen as y then the cost of notebook is twice the cost of pen . It means x - 2y= 0

2nd question s ans (i) a=2 b= 3 c= -9.35 . Like this u have to do all the questions
