Solve. 1/x+6-1/x-6
My answer is: -12/x^2-36
First, assuming that you do not have any typos, combine like terms.
1/x-1/x = 0
6-6 = 0
0 + 0 = 0
Solve. 1/x+5+2=5/x+5
My answer is: -3
Combine terms and treat both sides of the equation the same way.
1/x +7 = 5/x +5
Subtract 1/x and 5 from both sides.
2 = 4/x
Multiply both sides by x.
2x = 4
You should be able to proceed from there.
Subtract. Express your answer in simplest form. 13x/30-4x/15
My answer is: x/6
Convert to the lowest common denominator, which is 30.
13x/30 - 4x/30 = 9x/30
I hope this helps. Thanks for asking.
