Solve for b?

Question

a=(1/2)bc^2

Answer 1

Original equation
a = (1/2)bc^2

Your goal is to get b by itself, so you want to cancel anything on the same side as b...

Start by multiplying by 2 on both sides; this will cancel the 1/2:
2a = bc^2

Now divide by c^2 on both sides; this will cancel the the c^2 on the right:
2a / c^2 = b

Reverse the equation so b is on the left:
b = 2a / c^2

There's your equation solved for b.

Answer 2

B=2a/c^2

Answer 3

a=(1/2)bc^2 [Multiply both sides by 2}
2a = bc^2 [Divide both sides by c^2
2a/c^2 =b <---- and here's your answer.

Answer 4

a = (1/2) b(c^2)

Your first step is to get rid of that pesky fraction. Multiply both sides by 2, and that'll do it.

2a = b(c^2)

Now, you want to get b all by itself. To do that, you must *divide* both sides by c^2.

2a/(c^2) = b

Answer 5

divide both sides by .5 and c^2 to get
b=2a/c^2

Answer 6

a=(1/2)bc^2

It's the same as...

a=(bc^2)/2

then solve...

2a=bc^2

2a/(c^2)=b

Answer 7

(2a)/c^2 = b

Edit: c not equal to 0.
