Question

Which of the following is not a linear equation in one variable? A. 3x+y
B. 3z+4
C. 7y+2

Answer 1

Answer:

3x+y

Step-by-step explanation:

everyevery other linear equation contains a number which is necessary to find a solution A. doesn't contain it so it is not a linear equation

Answer 2

$\rm\red{ANSWER}$

3x + y is not the linear equation in 2 variable.

$\longrightarrow$It has 2 variables that are x and y. so , it is linear equation in 2 variable.

Other options -

$\implies$ 3z + 4 $\longrightarrow$ It has only one variable. So , it is linear equation in one variable.

$\implies$ 7y + 2 $\longrightarrow$ It has only one variable. So , it is linear equation in one variable.
