An equation of the form ππ₯ = π is called a linear equation with one variable or
unknown, here π and π are some numbers, π₯ βvariable. Is it true or false: A linear equation can have maximum one root.
False, when a=0;b=0 there are infinitely many solutions.

Vertical Angles
There are only π₯ red marbles and π¦ green marbles in a bag. The probability of randomly selecting a green marble is 3/7 . The marble is then returned to the bag, and 2 more red marbles and 3 more green marbles are added. Another marble is taken at random from the bag, and the probability of selecting a green marble is now 6/13 . Find the original number of red marbles and the original number of green marbles in the bag by constructing a system of equation.
x=12 , y=9
Which mathematician famously said, βDo not worry about your difficulties in mathematics; I can assure you mine are still greaterβ?
Albert Einstein
If HCF(a,b)=1 and HCF(a,c)=1, does it imply HCF(a,bc)=1? Explain.
Yes, because a and bc does bot have a common factor.
A quadratic equation in the variable π₯ is of the form ππ₯2 + ππ₯ + π = 0. Prove that one of the roots of a quadratic equation can be equal to zero if and
