Answer 1

Answer:

Step-by-step explanation:

let the marks got in maths be x

marks got in english =2x+30              ....................................eq1

x+2x+30=240

3x=210

x=70

put x=70 in eq 1

marks got in english=140+30=170

Answer 2

Answer:

Step-by-step explanation:

1/3x - 1/2y = 30 --------- ( eq 1 )

2x - 3y / 6 = 30

2x - 3y = 180

X + Y =240 -------- ( eq 2 )

2 ( x + y = 240)

=> therefore, 2x + 2y = 480

2x - 3y = 180

- 2x + 2y = 480

---------------------------

- 5Y = -300

Therefore 5y = 300

Y= 60

Therfore Arun got 60 Marks in English.
