Question

Which one is a linear equation in one variable?

• A. $3x-y=8$
• B. $3x-1=16$
• C. $5\times 3-1=14$
• D. $x^2-3x+1=0$

Answer 1

The correct option is B

$3x-1=16$

Equations that can be expressed in the form , $ax+b=c$ where $a,b,c$ are constants and $x$ is the only one variable.

In option (b) , $3x-1=16$ ,

$a=3,b=-1,c=16$

So, option (b) is the correct option
