8x+5y=9 3x+2y=4 | कक्षा 10 | कोई नहीं | गणित | संशय

8x + 5y = 9 , kx + 10 y = 15 .

3x+2y=4 ; & 8x+5y=9

6x+4y=5 9x+6y=8

8x+5y-11=0; 3x-4y-10=0

2x+3y=8 4x-5y=-6

2x+3y=5 6x+9y=10

If 8x + 5y = 9, 3x + 2y = 4, then the value of x and y are

4 x + 6y = 3 xy , 8x + 9 y = 5xy ( x ne 0 , y ne 0 )

Find graphically the solution sets of each of the following systems of inequalities : x + y le 6 2x + 5y ge -8 3x + 8y le 9 10x + 12y le 7 8x + 7y le 14 x, y ge 10

Find the values of (x+y ) , if (i) 3x + 4y = 11 , 4x + 3y = 10 (ii) 5x - 2y = 4 , x + 8y = 26
