Q4 of 87 Page 9

Find a number such that when 5 is subtracted from 5 times that number, the result is 4 more than twice the number.

Let the number is "x"


Then, five times the number will be = 5x 


And, two times the number will be = 2x


then, According to the question:


5x - 5 = 2x + 4


On transposing 2x to LHS and -5 to RHS,


5x - 2x = 5 + 4


3x = 9


x = 9/3


x = 3


 


Therefore the number is 3
