∙ 10y agoy + x = 4
y - 4 = x
y = -x + 4
y = x + 4
Since the slopes of the lines are negative reciprocals, the lines are perpendicular. Both lines passes through (0, 4), the y-intercept point.
Therefore, the system of equations has one solution, (0, 4).

What is the solution of the following system of equations y equals x plus 4 y equals -2x plus 1?
There are two solutions and they are: x = -1 and y = 3
What is the solution to x plus y equals -2?
There are infinitely many solutions, for example, x=-7 and y=5, because -7+5=-2
How many solutions does x equals y and y equals x have?
Infinitely many: they are the same line!
What does it mean if an equation equals 0 does it have one solution no solution or indefinitely many solutions?
It has infinitely many solutions.
What is the solution of 4y minus x equals 10?
The equation has infinitely many solutions.
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.
How many solutions does y equals 2x and y equals 2x-4 have?
There is no solution for those equations because the lines are parallel so, they never touch.
How many solutions of secx equals 2?
Infinitely many.
Do the equations X equals 4y plus 1 and X equals 4y-1 have the same solution?
x=4y+1 x=4y-1 No,they have different solutions.
What is the solution of the following system of equations y equals x plus 4 y equals -2x plus 1?
There are two solutions and they are: x = -1 and y = 3
Does this system of equations have one solution no solutions or an infinite number of solutions 2x - y equals 8 and x plus y equals 1?
Solve both equations for y, that is, write them in the form y = ax + b. "a" is the slope in this case. Since the two lines have different slopes, when you graph them they will intersect in exactly one point - therefore, there is one solution.
What is the solution to x plus y equals -2?
There are infinitely many solutions, for example, x=-7 and y=5, because -7+5=-2
What is the system of equations and enter the solution as an ordered pair 4x 7y equals 47 5x-4y equals -5?
Do you mean: 4x+7y = 47 and 5x-4y = -5 Then the solutions to the simultaneous equations are: x = 3 and y = 5
How many solutions does x equals y and y equals x have?
Infinitely many: they are the same line!
