Solve for x and y , `x[{:(2),(1):}]+y[{:(3),(5):}]+[{:(-8),(-11):}]=0`.

Text Solution

Verified by Experts

We have, `x[{:(2) ,(1):}]+y[{:(3),(5),:}]+[{:(-8),(-11):}]=0`
` rArr [{:(2x),(x):}]+[{:(3,y), (5,y):}]+[{:(-8)/(-11):}]=0`
`therefore [{:(2x,3y-8),(x,5y,-11):}]=[{:(0),(0):}]`
`rArr 2x+3y-8=0`
and `4x+6y=0`
x+5y-11=0
`rArr 4x+ 20y=44`
