Question

Finding the value of a variable in a linear equation that_____ the equation is called a ______ of the equation.

• A. satisfies
• B. root

Answer 1

Solutions of any linear equation.

An algebraic equation with two variables and both the variable have degree one then it is known as a linear equation involving two variables.

The standard form of a linear equation having two variables:

$ax+by+c=0$, where $a,b,c\in R$ and $a,b\ne 0$.

An example of linear equations in two variables is given as :

$-7x+y=8$

The value of variables $x$ and $y$are the roots of this linear equation.

The roots are also known as the solutions of linear equations.

Hence, finding the value of a variable in a linear equation that satisfies the equation is called a root of the equation.
