Linear equation is the equation in which the highest power of the variable is one. The solution of the given equation is (7,2). Hence the option 3 is correct.
The given linear equation in the problem area,
[tex]\begin{aligned}\\3x-2y &=17\;\;\;\;\;\;\;\;.......1\\x-3y &=1 \;\;\;\;\;\;\;\;\;\;.......2\\\end{align}[/tex]
The given equation are the set of the linear equation.
Linear equation is the equation in which the highest power of the variable is one.
Rewrite the equation 2 to get the value of variable x in terms of y,
[tex]\begin{aligned}\\x-3y &=1\\x &=1+3y\;\;\;\;\;\;\;\;.......3\\\\\end[/tex]
Put this value of x in the equation 1. Thus,
[tex]\begin{aligned}\\3(1+3y)-2y &=17\\3+9y-2y &=17\\7y &=17-3\\y &=\dfrac{14}{7} \\y &=2\\\end[/tex]
Thus the value of the variable y is 2. Put this in equation 3.
[tex]\begin{equation}\\x=1+3y\\x=1+3\times 2\\x=1+6\\x=7\\\\\end[/tex]
The value of the variable y is 7.
Thus the solution of the given equation is (7,2). Hence the option 3 is correct.
