5x - 3y = 8; 3x + y = 2​

Answer 1

Step-by-step explanation:

5x-3y=8..........equ.1

3x+y=2…........eq 2

from equ. 2

3x+y=2

y=2-3x.......equ. 3

now, on putting the value of y in eq. 1

5x-3y=8

5x-3(2-3x)=8

5x-6+9x=8

14x=8+6

x=14/14=1

Now , by putting the value of x in eq. 3

y=2-3x

y=2-3×1

y=2-3= -1 Ans

Answer 2

Step-by-step explanation:

5x-3y=8..........equ.1

3x+y=2…........eq 2

from equ. 2

3x+y=2

y=2-3x.......equ. 3

now, on putting the value of y in eq. 1

5x-3y=8

5x-3(2-3x)=8

5x-6+9x=8

14x=8+6

x=14/14=1

Now , by putting the value of x in eq. 3
