use paper

text math is awful

X = h/3(a+b)
X/h = 1/3(a+b)
h/X = 3(a+b)
(h/3X)-b = a
a = (h/3X)-b

🤔

I see what you’re doing wrong

Just multiply out the denominator first

Not the numerator

I have no idea what gwence was doing

il try what you said

She distributed first

Then removed the denominator

X = h/3(a+b)
3X(a+b) = h
a+b = h/3X
a = (h/3X)-b

there you go

oh hey it's quicker

same answer tho

wait I see where you went wrong

moving (a+B) to the Left hand side

did you divide

you didn't

I multiplies both sides by that value

h(a+b) needs to be moved to the LHS by dividing h(a+b) to remove (a+b)

you would be multiplying (a+b) * (a+B)

which would not remove it from the right hand side

divide instead

try again

if I divided I would get
X/3(a+b) = h/(3(a+b))^2

no that's what you'd get if you multiplied

try again

please do it on paper

so you can see what you're doing better

I see it fine

and it's wrong

ok

well il stay wrong i guess

@The Gwench what's that equation for

it's a simple solution

but has many tempting wrong answers

may I ask what math course you are in

None

you're done with math?
