10.724 = 2.127+2x
______ _______
1 2.127 - x
cross mutiply
(10.724)(2.127-x)=2.127+2x
distribute
22.82 - 10.742x = 2.127+2x
subtract 2.127 from both sides
-2.127 -2.127
20.693 -10.742x = 2x
add +10.742x or subtract -10.742x
+10.742x 10.742x
20.693 = 12.742x
divide 12.742 to get x by it's self
______ _______
12.742 12.742
there's your answer
1.624 = x!!!

Multiply both sides by (2.127 - x).
Isolate the variable 'x'.
Combine like terms.
Voila!
x = 1.625506759
(Depends on how many decimal places are called for)

10.724= [2.127 + 2x] / [2.127 - x]
10.724 [2.127 - x] = 2.127+2x
22.8099 -10.724x=2.127 + 2x
-12.724x = -20.6829
x =1.626

10.724= [2.127 + 2x] / [2.127 - x]
Muliply both sides by [2.127 - x]:
10.724*[2.127 - x]= 2.127 + 2x
Distribute 10.724:
22.810 - 10.724x=2.127 + 2x
Combine like terms:
20.683 = 12.724x
Divide both sides by 12.724:
x = 1.626

Multiply both sides by [2.127 - x].
Then solve for x.

10.724(2.127 - x) = 2.127 + 2x
2.127(10.724 - 1) = (2 + 10.724)x
x = 2.127(10.724 - 1) / 12.724
= 1.6255067.

add the x's together to get just one x then divide 2.127 by 2.127 to get one. then it will be 10.724=1x. divide both sides by 1 and u get 10.724=x and there is your answer.

10.724(2.127-2x)=2.127+2x
10.724*2.127-10.724*2x=2.127+2x
9.724*2.127=23.448x
x=20.560458/23.448
x=0.877 approx
