Question 549559
{{{7x+2(x-3)>12}}}

Let's first expand this 
{{{7x+2x-6>12}}}

And now let's collect like terms 
{{{9x-6>12}}}

And finally let's isolate for x:
{{{9x-6+6>12+6}}}
{{{9x>18}}}
{{{9x/9>18/9}}}
{{{x>2}}}




There you have it!


Some things to just be aware of -- if I were to divide or multiply by a negative number in any of my steps, I MUST SWITCH THE INEQUALITY SIGN THE OTHER WAY  (luckily I didn't have to, but in other examples you may have to)


Have a good one!
