Question

If πx+3y=25 write y in term of x and also find the two sol of this equation

Answer 1

How to write y in term of x : leave y in the left hand side.

$3y=25-\pi x$

∴ $y=\frac{25-\pi x}{3}$

Two solutions : substitute an easy number.

Take $x=0$, $x=2$.

∴ $(x,y)=(0,\frac{25}{3} ),(2,\frac{25-2\pi }{3} )$
