Question 90000
Find the x-intercept of:
{{{4x+2y = 12}}}
Remember, the x-intercept occurs at y = 0, so set y = 0 and solve for x.
{{{4x+2(0) = 12}}}
{{{4x+0 = 12}}}  
{{{4x = 12}}}  Divide both sides by 4.
{{{x = 12/4}}}
{{{x = 3}}} This is the x-intercept!


Check:
{{{4x+2y = 12}}}
{{{4(3)+2y = 12}}}
{{{12 + 2y = 12}}}  Subtract 12 from both sides.
{{{2y = 0}}}
{{{y = 0}}}
