Question 1092465: Identify the erroneous part/s of the computation which make/s the solution invalid. Then, present the correct solution in solving the rational equations below
1/4x + 1/ 2(x+1) = 1/3x
Solution: [ ( 1/4x + 1/2) = (1/3x) ] 12(x+1)
3(x+1) + 6 (x+1) = 4(x+1)
9x + 9 = 4x+4
5x=-5

You can put this solution on YOUR website! I am interpreting this as
(1/4x)+(1/(2x+1))=(1/3x)
one has to multiply both sides by the common denominator 12x*(2x+1), not just (2x+1)
3(2x+1)+12x=4(2x+1)
6x+3+12x=8x+4
10x=1
x=0.1 or 1/10
check
1/0.4 +1/1.2=1/.3
10/4+10/12=10/3
multiply everything by12
30+10=40 checks.
