Answer:

x=4/15

y=1/5

Step-by-step explanation:

3x+y=1 -----------(a)

2x-11y=3 ---------(b)

equation (a) multiplied by 2 and (b) multiplied by 3

6x+2y=2------------(c)

6x-33y=9 ----------(d)

substracting equation (c) from (d)

35y=7

y=7/35

y=1/5-------(e)

substituting y=1/5 in equation (a)

therefore,

3x+y=1

3x+1/5=1

15x+1/5=1

15x+1=5

15x=5-1

15x=4

x=4/15
