X-45\x<-4(multiply both sides by X to remove the denominator )
X-45<-4x (collect the like terms)
-45<-4x+x
-45<-3x(divide both sides by -3
-45\-3<-3\-3x
15>x

7/12 divided by 2/5 is 35/24
Answer:
= - 14 - 4√5/ 29
Step-by-step explanation:
(√3-√5)(√5+√3)/7-2√5
= √15 + 3 - 5 - √15/7 - 2√5
= - 2/7 - 2√5
= - 2/7 - 2√5 x 7 + 2√5/7 + 2√5
= - 14 - 4√5/49 + 14√5 - 14√5 - 20
= - 14 - 4√5/ 29
