Question

E) if a= (3 /5)-2x (7 /5)° find the value​

Answer 1

Answer:

Given 35x−4=52x

⇒35x−52x=4  [Transpose 52x to LHS and −4 to RHS]

⇒1525x−6x=4 [Takling LCM in LHS]

⇒19x=60

⇒1919x=1960  [Dividing both sides by 19]

⇒x=1960

Now, 2x−7=2∗1960−7 [Putting the value of x]

⇒19120−133=−1913 [Taking LCM]

Hence, the numerical value of 2x−7 is −1913.

Hope it helps
