You can put this solution on YOUR website!
You need consoling:
Being bad at math is like being a bad driver.
You're just not doing what the other drivers do
that make them good drivers. The teacher is mad
because you keep driving her car off a cliff.
All I can say is math never strays far from the
basics, and if you missed the basics somehow,
you have to back there- like back to parallel
parking. Don't worry if you're too young to drive-
I'm just using examples.
You're not born to be bad at math- you just got that
way
-7%283%2B2x%29+=+84
You MUST do the same thing to both sides of an equation
Divide both sides by -7
%28%28-7%29%2F%28-7%29%29%2A%283+%2B+2x%29+=+84%2F%28-7%29
3+%2B+2x+=+-12
Now subtract 3 from both sides
3+-+3+%2B+2x+=+-12+-+3
2x+=+-15
Divide both sides by 2
x+=+-7.5
Keep at it.
