Question

solve

Answer 1

x = 6/5 (can someone double check? i did this mentally :) )

Answer 2

Just use the rule

xy/x = y
or
5(2)/2 = 5

remembering that you need the same denominator to add or subtract fractions.

If you use the rule I just listed you can set all the fractions up to have the same denominator without changing their value

Answer 3

A. {0.25, 2}
B. {1/2, 2}
C. {1/2, 1}
D. {.25, 1}

Answer 4

I recommend reading what I wrote, this is fundemental algebra and you must know this. If you have any questions please ask.

Answer 5

so

(3)x/(x-1)(x) + 2(x-1)/x(x-1)

Answer 6

multiply each term by x(x - 1) which gives

3x + 2(x -1) = 4x(x-1)

expand and simplify

5x - 2 = 4x^2 - 4x

then 4x^2 - 9x + 2 = 0

solve the quadratic

(4x -1)(x-2)=0

then x = 1/4 or 2
