I notice that the ratio of the y-coefficient to the x-coefficient is the same in both
equations. I think that's enough to tell me that their graphs are parallel. So they
don't intersect, and viewed as a pair of simultaneous equations, they have no solution.

5x - 3y equals 23 7x - 4y equals 33?
Do you want the solutions to the equations? If so then: x = 7 and y = 4
What is the solution of the following system of equations 3y - 2x equals 3 y equals x?
x = y = 3
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
What is the common point of these equations x plus y equals 10 x-y equals 6?
16
What is the common point of these equations 2x plus 3y equals 12 and x - 3y equals -3?
(3, 2) because x = 3 and y = 2
How many solutions are there to the following system of equations 2x-y equals 2 AND -x plus 5y equals 3?
How many solutions are there to the following system of equations?2x - y = 2-x + 5y = 3if this is your question,there is ONLY 1 way to solve it.
How many solutions does the following system have x plus y equals 3 and 2x plus y equals 5?
It has 2 solutions and they are x = 2 and y = 1 which are applicable to both equations
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 are the solutions to -x squared plus 2x plus 4 and x-2?
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
What are the solutions to the equations 3x -5y equals 16 and xy equals 7?
Equations: 3x-5y = 16 and xy = 7 Solutions: (7, 1) and (-5/3, -21/5)
What are the solutions to the equations 7x-4y equals 13 and 2x-5y equals -4?
It works out that the solutions are: x = 3 and y = 2
How many solutions does 0 equals 0 have?
0 = 0 is an identity and not an equation. Equations have solutions, identities do not.
Solve the following system of equations express your answer as an ordered pair 2x plus 5y equals 16 and -5x minus 2y equals 2?
The solutions are: x = -2 and y = 4
What are the values called at which the equation equals zero?
They are called the solutions or roots of the equations.
Are there any solutions to the system of inequalities y equals 2x plus 3 and y equals 2x - 1?
There are no common points for the following two equations: y = 2x + 3 y = 2x - 1 If you graph the two lines, since they have the same slope, they are parallel - they will never cross.
What are 3 real rational solutions to this system of equations z equals x squared y equals z squared x equals y squared?
The two rational solutions are (0,0,0) and (1,1,1). There are no other real solutions.
How many solutions does this system of equations have 2x-3y equals -14 4x-6y equals -28?
The equations are identical in value, ie the second is merely twice the first...
