Question

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

• A. 2x + 3y = 10
• B. 2x = 3x + 4
• C. 2x = 3y + 4
• D. 2x + 4z = 5

Answer 1

The correct option is B 2x = 3x + 4

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.

So, linear equation in one variable will have equal sign,one variable and highest power of the variable is 1

So, according to the conditions 2x = 3x + 4 is the linear equation in one variable.
