Answer:
2x - 5 = 19
Explanation:
let the number be x , then 2times the number is 2x and
five less than this is 2x - 5
equating to 19 then gives the equation
2x - 5 = 19
to solve the equation , add 5 to both sides
2x - 5 + 5 = 19 + 5 ( simplify both sides )
2x = 24 ( divide both sides by 2 )
x =
, that is
x = 12
