4x+3y=13 is your equation start off by plugging in the points (4, -1) you'll see 4*4+3*-1=13 and you've got your answer. I hope i helped :)
If you mean: 2y+5x = 13 and 2y-3x = 5 then it works out that x = 1 and y = 4
(2,3)
1 + 12 = WHAT
If: 2x = 26 Then: x = 13
If you mean: slope of -13 and point of (5, 7) then the equation is y = -13x+72
13
13
There are infinitely many ordered pairs tat are solutions. They are all points on the line represented by 5x-6y = 13

Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals". There appear to be two equations, but no ordered pair.
There are an infinite number of them.Here are a few:X . . . . Y-3 . . . -1-2 . . . -0.6-1 . . . -0.20 . . . . +0.21 . . . . 0.62 . . . . 13 . . . . 1.45 . . . . 2.210 . . . 4.2
It would be (13, 47).
If you mean: y = 4x-2 and y = x+13 then x = 5 and y = 18
You can't find this out by solving an equation, but you can by solving a system of two linear equations. Basically, you would need to know the equations for both of the lines before you began. Then, you would solve one of those linear equations for one of the variables in terms of the other, like y in terms of x. Then, you'd plug that value of y, in our case, into the other equation and solve for x. Then you'd plug that value of x, which is now a number, back into the original equation to get a numerical value for y. Your intersection point would then be the ordered pair (x,y). Here's an example:2x + 14y = 8,-6x + 10y = 4.Solve the first equation for y:y = (4/7) - (1/7)x.Plug that value for y into the second equation:-6x + (40/7) - (10/7)x = 4.Solve for x:(10/7)x + (42/7)x = (40/7) - (28/7),(52/7)x = (12/7),x = (12/52) = (6/26) = (3/13).Plug that value of x into the first equation:(6/13) + 14y = 8,14y = (98/13),y = (98/182) = (49/91) = (7/13).So the point at which those two lines intersect would be the ordered pair (3/13,7/13).Finally, it's usually worth while to verify your answer by plugging these values into the original equations.2(3/13) + 14(7/13) = (6/13) + (98/13) = (104/13) = 8, so the first one's right.-6(3/13) + 10(7/13) = -(18/13) + (70/13) = (52/13) = 4, so that one's right too.
Dear Questioner its not able to solve two variables for one equation, give one more equation. Thanks

6xy=13 y=13/6x You may be confused at this point because your graphing calculator graphs a line when you plug in this equation. What your calculator is doing is (13/6)x=y which is indeed a line. However, you are working on inverse variations. Plug this into your calculator y=13/(6x) How is that different? Just look at the graph.
If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
