2x-3y=7,5x+y=9

Asked by yadlapallieswarrao | 2nd Nov, 2021, 09:05: PM

Expert Answer:

2x - 3y = 7   ... (i)
5x + y = 9    ... (ii)
Multiplying (ii) by 3, we get
15x + 3y = 27  ... (iii)
Adding (i) and (iii), we have
17x = 34
x = 2
Putting the value of x in (ii), we get
5(2) + y = 9
Therefore, y = -1
