whats your Q????

the one above

you need numbers or something

?????

all it says is solve for the indicated variable. which appears to be b2

\[A=\frac{ 1 }{ 2h } (b1 + b2) \]

ok just to be clear i will multiply \[\frac{ 1 }{ 2h }\] by (b1+b2)
we have A=b1/2h + b2/2h

ok, i am following you

to get rid of 2h on hte right side we multiply by 2h so >>> A(2h)=(2h)(b1/2h + b2/2h)

simplifying the equation we get>>>>> 2hA=b1+b2

are we clear??

yes, i am reading what u wrote right now

good

thanks

and finally 2hA-b1=b2.

thank you

your most welcome :)

try to think what operators you can use to get rid of fractions so you can simplify it.

ok. i will, thanks again
