What have I done wrong in my simultaneous equation if I end up with x equals x?

You have used an equation which is actually the same and tried to use that to solve for your two unknowns. The two equations must be different - you should not be able to transpose one to be equal to another, so therefore if you graphed the two equations for example on the number plane they would be different graphs. The point(s) of intersection would be your solutions.

9x-5y-4 equals 0 Solve for y?
Can't be done unless you have another equation with the same x and y. Then you would solve for simultaneous equations.
What should be done to both sides of the equation in order to solve equals -12.4?
Multiply by 4
61x square plus 1 equals y square?
61x^2 + 1 = y^2.What do you want done with that equation?
What states that the solution to an equation does not change when the same number is subtracted from both sides of the equation?
This is the rule of addition which states that if equals are added to equals, the sum is equal. It also applies to subtraction. The rule of multiplication is similar: if equals are multiplied by equals , the result is equal. It also applies to division. These are the basic rules of algebra ; In fact that is what algebra means, from the Arabic "al jabr" : what is done to one side, if done to the other, nothing is changed.
Can the equation x equals y-siny be rearranged in terms of y?
Yes: it is already in terms of y so nothing needs to be done.

What is the meaning simultaneous?
Existing, happening, or done, at the same time; as, simultaneous events.

Yes: it is already in terms of y so nothing needs to be done.
-7x plus 7y equals -49?
-x + y = -7. There is nothing more that can be done with just one equation and two unknowns.
What operation must be done to both sides of the equation to solve p plus negative three and seven-ninths equals five-sixths?
yes
What is the force applied in moving an object to a distance of 8m if the work is done on it is 640 joule?
The equation that links force, distance and work isWork done = Force X DistanceThis can be rearranged to giveForce = Work done / DistancePlug the values from the question into the equation to give the calculationForce = 640/8Therefore the force equals 80 Newtons
How do five 5s equals 24?
5x5x5 equals 125 so that 3 fives used 125-5 equals 120 that's 4 used then 120/5 equals 24 that's 5 Done Easy as that Here's the equation ((5x5x5)-5)/5
