Question

A student was asked to add 6 to a number and then multiply it by 5. By mistake he added 5 and multiplied it by E
getting the result as 210. What should have been the actual result?​

Answer 1

Answer:

5(210/E+1)

Step-by-step explanation:

let a number be x.

first equation is:

6 is added to a number =( x + 6)

and then multiplied by 5 = 5(x+6)

consider , 5(x+6) be equation (1).

second equation is:

he mistakenly added 5 to a number = (x+5)

and then multiplied by E =

the result is, 210 = E(x+5) be equation (2).
