Question

Which of the following is a linear equation in
variable?
A.
{(3x - 1) }^{2} = 9 {x}^{2} + 4x - 4(3x−1)
2
=9x
2
+4x−4
B.
{(9x - 2)}^{2} = 5x - 5 {x}^{2} + 5(9x−2)
2
=5x−5x
2
+5
C.
2 {x}^{2} = 3x - 22x
2
=3x−2
D.
None of these​

Answer 1

Answer:

D

none of these I think its right

Answer 2

Step-by-step explanation:

actually question is not actually clear,if in the question it is required to find out that which of the following is linear equation in one variable then,firstly solve each equation one by one.atlast the equation having x^ 1 max will be the linear equation.

it is not necessary that any equation containing x^2 as max power can not be linear,it may be possible if after solving the equation term containing x^2 cancels out.
