Question

Express $x$ in terms of $y$ and Check whether $x=3,y=2$ is a solution of the equation $\frac{x}{3}=5-2y$

Answer 1

$\frac{x}{3}=5-2y$

$\therefore x=3(5-2y)$

$\therefore x=15-6y$

$\therefore$ Now checking : -

$3=15(-6(2\left)\right)$

$\therefore 3=15-12$

$\therefore 3=3$

$\therefore (x=3,y=2)$

is a solution
