3xy - 3xy = 0
13-3x = 43 -3x = 43-13 -3x = 30 x = -10
This is the same as: 13-2b = 21 -2b = 21-13 -2b = 8 b = -4
Solved for y: y=(3x-13)/5 Solved for x: x=(5y+13)/3
y = 2x -1 y = 5x -13 So: 5x -13 = 2x -1 5x -2x = 13 -1 3x = 12 x = 4 and by substituting y = 7
3xy-4x + 15y-20 Sol: As there are no number are same. So -4x-3xy +15y-20 -------------------- -4x-3xy+15y-20
no
No, it is not.
X +13 equals 22, X equals nine

yes 3xy=6
2x^2+3xy-4y2(4)+3(2)(-4)-(4)(-4)8-24+16=0
3xy - 3xy = 0
12 + 5 equals...

542 X 13 = 7046
x - 13 = 5 x = 18
