Question

Which of the following is a solution of
$x+5y-18=0?$

• A. (2,3)
• B. (4,3)
• C. (3,3)
• D. None of these

Answer 1

The correct option is C

(3,3)

If a given point is the solution of the linear equation in two variable, then it satisfies the equation.

Substitute $x=3,y=3$

$x+5y-18=0$

$LHS=3+5\left(3\right)-18=0$

$\Rightarrow LHS=RHS$

$\therefore$ (3 3) satisfies the given linear equation.

$\Rightarrow$ (3,3) is the solution of the equation.
