Answer» 2x-3y =12________(1) 2x +4y = -2_______(2) Value of x & y Subtract equ(1) &equ(2) ➡ -3y - 4y = 12 + 2 ➡-7x = 14 ➡x = 14/(-7) ➡x = -2 Keep value of x in equ(1) ➡2 × -2 - 3y = 12 ➡-3y = 12 + 4 ➡-3y = 16 ➡y = 16/(-3) ➡y = -16/3 Value of x = -2 Value of y = -16/3 _________________ Keep Value of x & y in equ(1) ➡2 × -2 - 3 × -16/3 = 12 ➡-4 + 16= 12 ➡12 = 12 L.H.S. = R.H.S. We can SAY that our solution is RIGHT. _________________ |
