Answer:
x = 2 , y = 3
x = 2 , y = -3
x = 3, y = 2
x = 3 , y = -2If 2x + 3y = 12 and 3x - 2y = 5 then
Explanation:
If the system of equations kx - 5y = 2 and 6x + 2y = 7 has no solution, then k=
-10
-5
-6
-15For what value of k, do the equations 3x - y + 8 = 0 and 6x - ky + 16 = 0 represent coincident lines ?
1/2
-1/2
2
-2If 4x + 6y = 3xy and 8x + 9y = 5xy then
x = 2, y = 3
x = 1 , y = 2
x = 3 , y = 4
x = 1 , y = -1
