What is the X-in intercept of the line 6x + y = 18

Keith_Richards [23]

$\boxed{x=3}$

Step-by-step explanation:

The Standard Form of the equation of line is given by:

$Ax+Bx=C \\ \\ For \ A, \ B, \ C\ Real \ Constant \\ and \ A>0$

So:

$6x+y=18 \\ \\ is \ written \ in \ standard \ form$

The x-intercept can be found setting $y=0$ :

$6x+(0)=18 \\ \\ Isolating \ x: \\ \\ 6x=18 \\ \\ \boxed{x=3}$
