2X-3Y = 10
2X = 10+3Y
X = 10+3Y/2...........(1)
XY = 16
(10+3Y/2) ×Y = 16
10Y +3Y² = 32
3Y² +10Y-32 = 0
FACTORIES THIS EQUATION AND FIND Y. AFTER FINDING THE VALUE OF Y THEN PUT THE VALUE OF Y IN THE VALUE OF X THEN U WILL GET THE VALUE OF X.AND THEN PUT THE VALUE OF X AND Y IN THAT EQUATION THAT WE HAVE TO FIND
