It is known that the system of equations 3x-2y = 4mx + NY = 7 and 2mx-3ny = 195y-x = 3 have the same solution. Find the values of M and n Don't: The equations of 3x-2y = 4 and 5y-x = 3 are connected to solve the x y value In the solution of the value into the two m n equations to form a binary system of first-order equations about M n The specific value is X=2 Y=1 M=4 N=-1 If you understand, please answer~

First solve the equation 3x-2y = 41, 5y-x = 3,2,2 * 3, get 15y-3x = 9,3,3 + 1 = (3x-2y) + (15y-3x) = 4 + 9. Open the equation, cut off 3x, and get 13y = 13. So y = 1, take y = 1 as 1, get x = 2, and then bring into the equations MX + NY = 7 and 2mx-3ny = 19

It is known that the solutions of the equations 3x-2y = 11; MX + 3Y = 29 and 4x-5y = 3; 5x NY = 20 have the same solutions, so find the solutions of x ^ 2 + n ^ 2

First solve the equations {3x-2y = 11 4x-5y = 3
The solution is: {x = 7, y = 5
From x = 7, y = 5 generation MX + 3Y = 29, 7m + 15 = 29, M = 2
When x = 7, y = 5 generations, 5x NY = 20, 35-5y = 20, n = 3
It seems to be m 2 + N 2, right?
∴m²+n²=4+9=13

It is known that the solutions of the equations [2x + 5Y = - 6, mx-ny = - 4} and {3x-5y = 16, NX + my = - 8} have the same solution, so find the value of the algebraic formula 3M + 2n Quick. I'll use it for my speech

simultaneous equation:
2X+5Y=-6,
3X-5Y=16
The solution is: x = 2, y = - 2
Replace the solution with:
MX-NY=-4,
NX+MY=-8
The solution is: M = n = - 3,
3M+2N=5M=-15

We know the system of equations about X and y 3x−2y＝11 MX + 3Y = 29 and 4x−5y＝3 If the solution of 5x − NY = 20 is the same, find 2Mn M2 + N2

It is concluded that:
3x−2y＝11①
4x−5y＝3② ，
The solution is as follows:
x＝7
y＝5 ，
The result is as follows:
7m+15＝29
35−5n＝20 ，
The solution is: M = 2, n = 3,
Then the original formula = 12
4+9=12

If x = 2, y = 1 is the solution of the system of equations MX + NY = 3 mx-2ny, find m, n

Put x = 2, y = 1, and you get
2m+n=3
2m-2n=2
Solution, get
m=4/3
n=1/3
Remember to take the answer
I don't know. Ask on hi

Two students a and B solve a binary system of first order equations about X and Y {1. MX + NY = 16,2. NX + my = 1} According to the above information, can you find the solution of the original equation? If you can, please solve the equation group; if not, please explain the reasons

Student a made a mistake in equation 1, which shows that x = - 1, y = 3 is the solution of the equation NX + my = 1
∴-n+3m=1
Student B copied equation 2 wrong, which shows that x = 3, y = 2 is the solution of equation MX + NY = 16
∴3m+2n=16
By the system of equations
-n+3m=1
3m+2n=16
Results: M = 2, n = 5
The solution of the original equations is x = - 9 / 7, y = 26 / 7
