Vedclass · Answer

(B) linear equation in two variables is an equation of the form $ax + by + c = 0$,where $a$,$b$,and $c$ are real numbers and $a$ and $b$ are not both zero.In this equation,the variables $x$ and $y$ must have a degree of $1$.Let us analyze the options:$A) x = 3y - 1$ can be written as $x - 3y + 1 = 0$,which is a linear equation in two variables.$B) x^2 - 5 = 0$ is a quadratic equation in one variable because the degree of $x$ is $2$ and the variable $y$ is absent.$C) y = 2x + 3$ can be written as $2x - y + 3 = 0$,which is a linear equation in two variables.$D) x - y = 0$ is a linear equation in two variables.Therefore,$x^2 - 5 = 0$ is not a linear equation in two variables.

Part $I$	Part $II$
$1.$ The solution of $2x - y = 4$ and $3x - 2y = 5$	$a.$ $x = 3, y = 2$
$2.$ The solution of $5x - y = 14$ and $4x - 3y = 9$	$b.$ $x = 3, y = 1$
$3.$ The solution of $4x - 3y = 5$ and $3x - y = 5$	$c.$ $x = 2, y = 1$
$4.$ The solution of $3x - 2y = -1$ and $2x - 5y = -8$	$d.$ $x = 1, y = 2$
