Question

Which of the following is a linear equation in one variable?
i.x² + 1 = 3
ii.y² + xy + 1= 5
iii.2y + 2 =3 +y
iiii.4

Answer 1

Answer:

iii. 2y + 2 = 3 + y

Step-by-step explanation:

2y + 2 = 3 + y

2y - y = 3 - 2

y = 1

Answer 2

Question:-

Which of the following is a linear equation in one variable?

i.x² + 1 = 3

ii.y² + xy + 1= 5

iii.2y + 2 =3 +y

iiii.4

Answer:-

A linear equation in one variable is an equation that can be written in the form ax b c + = , where a, b, and c are real numbers and . Linear equations are also first-degree equations because the exponent on the variable is understood to be 1.

Given:-

$\sf\fbox{2y + 2 =3 +y}$

Solutions:-

$2y + 2 = 3 + y$

$2y - y = 3 - 2$

$3 - 2 = 1$

$y = 1$

AnsWeR:-

$\sf\fbox{y = 1}$
