Do the equations 2x plus 4y equals 9 and -4x-8y equals 4 have a solution?

No, the two lines are parallel.
If the lines are parallel they have no solution; if the lines are the same line then there are infinitely many solutions - all the points on the liens.
2x + 4y = 9
-4x - 8y = 4
The second equation can be divided through by -2 giving the equations:
2x + 4y = 9
2x + 4y = -2
Left of the equal signs (containing unknown x and y) are the same, but right of the equal signs (containing just numbers) are different. Thus the second line is parallel to the first line and they have no points in common and thus no solution.

When will be the linear equations a1x plus b1y plus c1 equals 0 and a2x plus b2y plus c2 equals 0 has unique solution?
When (the graph of the equations) the two lines intersect. The equations will tell you what the slopes of the lines are, just look at them. If they are different, then the equations have a unique solution..
What is the solution of 3x plus 7y-c equals?
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
What kind of line is this equation 2y plus 4 equals 10 y equals -2x plus 5?
There are two equations in the question, not one. They are the equations of intersected lines, and their point of intersection is their common solution.
What is equation of 3x plus 2y equals 8 and 5x plus 2y equals 12?
Both of them are equations!The solution is (x, y) = (2, 1).
Answer this equations x plus 42y equals 4?

The solution to the system of equations y equals 2x and y equals -x plus 3 is?
x = 1 and y = 2
Is there a no solution in y equals x-1 and y equals -x plus 1?
In the equations Y=X-1 and Y=-X+1, the solution is (1,0)
What is the solution of the system 2x plus 3y equals 2 and 4x plus 6y equals 4?
That system of equations has no solution. When the two equations are graphed, they turn out to be the same straight line, so there's no such thing as a single point where the two lines intersect. There are an infinite number of points that satisfy both equations.
