@jadasmi Hi,

\(\huge \color{red}{\text{Welcome to Open Study}}\ddot\smile\)

Is your question complete? can u please verify.
solve for what?

Answer 5

its h(b1+b2) divided by 2

Answer 6

ok, i think you need to solve for some variable like h, or b1 or b2
can u tell me which topic does this question belong?
or can u post a screenshot of the question ?
so that we can help you better

Answer 7

ok im solveing for b1 the formula is a=h(b1 + b2) divided by 2

Answer 8

see, now this is correct question :)
to isolate b1, we need to bring everything that is with b1 to other side.
2 is divided, so now can u multiply 2 on both sides and tell me what u get ?

Answer 9

o divide b1 to bot sides

Answer 10

nopes,
a= h(b1+b2) / 2
so
2a = h(b1+b2) <---multiplying 2 on both sides
did u get this ?

Answer 11

so i divide 2 to h

Answer 12

what do i divided to

Answer 13

since h is multiplied, to get rid of h, you divide h on both sides. ok ?
so
2a/h = b1+ b2
did u get this ?

Answer 14

yess

Answer 15

now since b2 is ADDED to b1, to get rid of it, we SUBTRACT b2 from both sides,
what u get ?

Answer 16

i got 0

Answer 17

lol :P
2a/h = b1+b2
2a/h - b2 = b1
so u get b1 = 2a/h -b2
got this ?

Answer 18

that would be your final answer

Answer 19

ok i got it

Answer 20

great :)
