Answer:

x= -10

y= -4

Explanation:

Given data

3x+1=8y----------------1

11y-3x=-11--------------2

rearange

3x-8y=-1------------------1

-3x+11y=-11---------------2

add 1 and 2

3x-8y=-1------------------1

-3x+11y=-11---------------2

0+ 3y= -12

y= -12/3

y= -4

put y= -4 in 2

11y-3x=-11

11(-4)-3x=-11

-44-3x=-11

-44+11=3x

-33= 3x

x= -33/3

x= -10
