∙ 14y agoSubstitute for y: x + (-x - 4) = 4
ie x - x - 4 = 4
ie -4 = 4
That does not compute. No solution.

Which is a solution to the equation below- 2x equals 2 plus 2y?
There are no candidates below, so none of them. There are an infinite number of solutions to the equation, and from here, we can't see which ones are on your list of choices.
What are the solutions to the equation y equals -x plus 7?
The solution set consists of the infinite number of points that lie on the straight line y = -x + 7 or x + y = 7.

How do you recognize when an equation has no real solution or an infinite number of solutions?
It depends on the equation. Also, the domain must be such that is supports an infinite number of solutions. A quadratic equation, for example, has no real solution if its discriminant is negative. It cannot have an infinite number of solutions. Many trigonometric equations are periodic and consequently have an infinite number of solutions - provided the domain is also infinite. A function defined as follows: f(x) = 1 if x is real f(x) = 0 if x is not real has no real solutions but an infinite number of solutions in complex numbers.
If a system has an infinite number of solutions does it follow that any ordered pair is a solution?
No, this is not necessarily the case. A function can have an infinite range of solutions but not an infinite domain. This means that not every ordered pair would be a solution.

How many solutions does 2 equals y have?
In terms of y alone, just one solution. In the context of the Cartesian plane (or spaces in higher dimensions) an infinite number.
Do the equations x equals 4y plus 1 and x equals 4y-1 have the same solution. How might you explain your answer to someone who has not learned algebra?
Each of these have an infinite number of solutions. Never can they be equal.
Does this system of equations have one solution no solutions or an infinite number of solutions x - 2y equals -6 and x-2y equals 2?
x - 2y = -6 x - 2y = 2 subtract the 2nd equation from the 1st equation 0 = -8 false Therefore, the system of the equations has no solution.
