One number is 33 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 345 , find the numbers.

Ok just another guessing game on # to start with I tried many but will only show correct sneer to save time and space

my 1st # = 7

7x33=231. (33 times a first number)

means that 231 is second #

7+100 = 107 (3rd # is 100 more than 1st number)

means 107 is 3rd number

so add them all together

231+107+7 = 345
