You can put this solution on YOUR website!
7x%2B2%28x-3%29%3E12
Let's first expand this
7x%2B2x-6%3E12
And now let's collect like terms
9x-6%3E12
And finally let's isolate for x:
9x-6%2B6%3E12%2B6
9x%3E18
9x%2F9%3E18%2F9
x%3E2



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!
