In a class test, the sum of Shefali’s marks in Mathematics and English is 30. Had she got 2 marks more in Mathematics and 3 marks less in English, the product of their marks would have been 210. Find her marks in the two subjects.

Let,
Marks in maths=x
Marks in english=y

So,
x+y=30———(I)

2 more marks in maths =x+2
3 less marks in english=y-3
Product of two no. (x+2)(y-3)

So,
(x+2)(y-3)=210
xy-3x+2y-6=210
xy-3x+2y=216—————(II)

Solve these two equation by subsitution method……..
