Verify that `"x"=3/4,"y"=8/9and "z"=-5`
Advertisements
उत्तर
`"x"=3/4,"y"=8/9and "z"=-5`
Using, `"x"xx("y"-"z")="x"xx"y"-"x"xx"z"`
⇒`3/4xx(8/9-(-5))=3/4xx8/9-3/4xx(-5)`
⇒`3/4xx((8xx1)/(9xx1)+(5xx9)/(1xx9))=2/3+15/4`
⇒`3/4xx((8+45)/9)=(2xx4)/(3xx4)+(15xx3)/(4xx3)`
⇒`3/4xx53/9=(8+45)/12`
⇒`53/12=53/12`
