1 / (1.2-X) + 1/x = 5


not for me someone ask me help


thanks

Hi,

1 / (1.2-X) + 1/x = 5
1 / (1.2-X) = 5 - 1/x
1 = (1.2 - X)(5 - 1/x)
1 = 6 - 1.2/x - 5X + X/x
1 - 6 + 1.2/x = X(1/x - 5)
X = (-5 + 1.2/x) / (1/x - 5) = (1.2 - 5x) / (1 - 5x)

friend said X its the same variable

theres no small or big


X

Then I would find a common denominator on the left hand side first.
After that, combine everything on the left hand side into 1 fraction.
Then multiply both sides by the denominator.
Then move everything to one side so it's set equal to zero.
On a quick glance, it looks like you'll have a quadratic equation, So you can use the quadratic formula to solve for your x-values.

agreed, except would change the first line to:

multiply both sides with both denominators, ie (1.2-x)x then consolidate
