Question

which of the following number is linear equation in one variable
(a) z²+1=0
(b) xyz-1=0
(c) x-1y
(d) 3x+4=0​

Answer 1

a). z²+1=0

hope it will help you

Answer 2

The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution. For example, 2x+3=8 is a linear equation having a single variable in it. Therefore, this equation has only one solution, which is x = 5/2.

So your answer will be ----->

Option (d) 3x + 4 = 0.
