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.
Do you want the solutions to the equations? If so then: x = 7 and y = 4
x = y = 3
Do you mean: 4x+7y = 47 and 5x-4y = -5 Then the solutions to the simultaneous equations are: x = 3 and y = 5
(3, 2) because x = 3 and y = 2
16
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.
It has 2 solutions and they are x = 2 and y = 1 which are applicable to both equations
There are two solutions and they are: x = -1 and y = 3
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
Equations: 3x-5y = 16 and xy = 7 Solutions: (7, 1) and (-5/3, -21/5)
It works out that the solutions are: x = 3 and y = 2
The solutions are: x = -2 and y = 4
0 = 0 is an identity and not an equation. Equations have solutions, identities do not.
They are called the solutions or roots of the equations.
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.
The two rational solutions are (0,0,0) and (1,1,1). There are no other real solutions.
The equations are identical in value, ie the second is merely twice the first...
