(3,-1)
Step-by-step explanation:
2x + 3y = 3 Â (I)
7x - 3y = 24 (II)
Add equation (I) & (II) and y will be eliminated and we can find the value of 'x'
(I) Â Â Â Â 2x + 3y = 3
(II)    7x  - 3y = 24  {Add}
     9x      = 27  {Divide both sides by 9}
          x = 27/9
x = 3
Plugin x = 3 in equation (I)
2*3 + 3y = 3
 6 + 3y = 3
Subtract 6 from both sides
 3y = 3 - 6
 3y = -3
Divide both sides by 3
  y = -3/3
y = -1
