Question 210372
{{{8x-4y=12}}}
First, get the y terms alone on one side of the equation. Do this by adding -8x to both sides. Note this does not change the validity of the equation, since you did the same thing to both sides of the equals sign:
{{{8x-8x-4y=12-8x}}}
Simplify the Left Side:
{{{-4y=12-8x}}}
Now divide each side by -4:
{{{-4y/-4=(12-8x)/-4}}}
Simplify:
{{{y=12-8x)/-4}}}
{{{highlight(y=2x-3)}}}
