Sweet, thanks a bunch
Here's another horrendous math problem:
A= B/2+C/2 solve for B >_>"
I know the answer is B=2A-C but idk how to get that :l
It's just a matter of setting the equation correctly. You're trying to solve for B, so the first step is to get the B variable by itself on one side of the equation.
A = B/2 + C/2
The easiest way is to subtract C/2 from both sides as if you were subtracting any whole number.
A - C/2 = B/2 + C/2 - C/2
That leaves us with:
A - C/2 = B/2
Now your goal is to solve for B, not B/2, so you multiply both sides of the equation by 2.
2 * (A - C/2) = 2 * (B/2)
Now we have:
2A - C = B
Which can also be written:
B = 2A - C.
And there we go. I mathed.
