Answer:
2x^2 / (3x-1)(x-2)
Step-by-step explanation:
You can simplify any rational expression (fraction/fraction) or (fraction/number) or
(number/fraction) or even (number/number) by using
KEEP-CHANGE-FLIP
KEEP the first fraction (or the one on top), CHANGE the ÷ to times. FLIP over the last fraction (or bottom expression) see image.
Keep the x/3x-1 the same, change to multiplication. Flip over the second term to be 2x / x-2.
To multiply, you multiply straight across: top×top and bottom×bottom. See image.
(the very small final answer is just in case you are expected to multiply out the denominator. I think the factored form is neater. See image.
Answer:
see explanation
Step-by-step explanation:
1
x - 4 = 20 ( multiply through by 3 to clear the fraction )
2x - 12 = 60 ( add 12 to both sides )
2x = 72 ( divide both sides by 2 )
x = 36
2
4 =
( multiply both sides by 2 to clear the fraction )
8 = - 1 + x ( add 1 to both sides )
9 = x
3
12(x + 9) = - 108 ( divide both sides by 12 )
x + 9 = - 9 ( subtract 9 from both sides )
x = - 18
4
5x + 14 = - 7 ( subtract 14 from both sides )
5x = - 21 ( divide both sides by 5 )
x = -
= - 4.2
