<PRE><B>Question 580516</B>
To find the x-intercept, plug in {{{y=0}}} and solve for x



{{{4x+2y=12}}} Start with the given equation.



{{{4x+2(0)=12}}} Plug in {{{y=0}}}.



{{{4x+0=12}}} Multiply {{{2}}} and 0 to get 0.



{{{4x=12}}} Simplify.



{{{x=(12)/(4)}}} Divide both sides by {{{4}}} to isolate {{{x}}}.



{{{x=3}}} Reduce.



So the answer is choice B</PRE>
