Let X = your current age.
therefore:
. 4x + (2x - 5) = 55
. 6x - 5 = 55
Take 5 the other side of the (=) sign
. 6x = 60
Divide by 6 on both sides
. x = 10
therefore, you're 10 years old.

let the age be'x'
then 4 times the age is so, 4x
& 5 less than twice your age is 2x-5
now 4 times the age increased by 5 less than twice ur age
is 4x+2x-5=55
then 6x=50
there fore x=10
hope this is right if the assumption of the question is right

4a + 2a - 5 = 55
6a = 55+5 = 60
a = 60/6 = 10 #
