Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals".
There is no symbol between 5x and 4. Also, it is necessary to define either the domain (possible value of x) or range (possible values of y) since otherwise there are infinitely many ordered pairs.
They are all the pairs you make where (x = any number) and (y = 4).
x = 3 and y = -4
5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
Great. A multiple choice question without the choices.
If -4 + 5x = 6, 5x = 6 +4 = 10 or x = 2.
5x=4y=-20 x=-4 y=-5 (-4,-5) is the ordered pair
(1,6) and (4, -3).

x = 3 and y = -4
5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
(0,4) and (-2, 0)
Great. A multiple choice question without the choices.
5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
If -4 + 5x = 6, 5x = 6 +4 = 10 or x = 2.
4 + 5x = 1 5x = 1 - 4 5x = -3 x = -3/5 x = -0.6
There are an infinite number of ordered pairs. Any point on the straight line which passes through (0,4) and has a gradient of -2 will be an ordered pair for the equation.
The solutions are: x = -2 and y = 4
