Multiply both sides by 2, then add 130 to both sides and you will have your answer ;)
zarkam21 (zarkam21):
By 2 or 1/2
OpenStudy (zyberg):
By 2
OpenStudy (zyberg):
That was my mistake back then ;)
In other words you are dividing both sides by 1/2.
zarkam21 (zarkam21):
Well for 65, it would be 32.5

65*2 = 130
65/(1/2)=130
zarkam21 (zarkam21):
Okay so the other side would be 130 right, because 130*2=260 and 260/1/2=130
jhonyy9 (jhonyy9):
1
65 = --- * (adc -130)
2
this is your equation right wrote ?
zarkam21 (zarkam21):
Yes
jhonyy9 (jhonyy9):
so from this result
2*65 = adc -130 yes ?

OpenStudy (zyberg):
65=1/2(adc-130)
130 = adc - 130
adc = 260
OpenStudy (zyberg):
65/ (1/2) = ((1/2)/(1/2))*(adc -130)
130 = adc - 130
260 = adc - 130 +130
zarkam21 (zarkam21):
Ohh okay
jhonyy9 (jhonyy9):
@Zyberg please dont give directly right answers please - this is the rule of OS
@mathmate please
zarkam21 (zarkam21):

@jhonyy9 I didn't. I told her how to get the answer and she said that it's 260, but she obtained it in a wrong way, so I showed her the right way.
zarkam21 (zarkam21):
She showed me the process
jhonyy9 (jhonyy9):
ok. sorry
zarkam21 (zarkam21):
So this would be 207
zarkam21 (zarkam21):
27=1/2(dgf-153)
