C and D
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.
Add the two equations together. This will give you a single equation in one variable. Solve this - it should give you two solutions. Then replace the corresponding variable for each of the solutions in any of the original equations.
why will the equations x+14=37 and x-14=37 have different solutions for x
The solutions work out as: x = 52/11, y = 101/11 and x = -2, y = -11
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.
Just one.
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
1
Through a process of elimination and substitution the solutions are s = 8 and x = 5
It has 2 solutions and they are x = 2 and y = 1 which are applicable to both equations
Infinite, both equations are equivalent and all possible solutions can be represented on the graph y = 4 - x
Only one: (3,-2)
None. When these two equations are graphed, the two lines are parallel. Since they never intersect, there is no point that satisfies both equations.
There are two solutions and they are: x = -1 and y = 3
We believe that those equations have no real solutions, and that their graphs therefore have no points of intersection.

They are simultaneous equations and their solutions are x = 41 and y = -58
