Let a be the first number and b the second number then,
(1) a = 8 + 2b and (2) a + b =123
From (2) a = 123 - b substituting for a in (1) gives :-
123 - b = 8 + 2b , 3b = 115, b = 115/3 = 38⅓.
and substituting for this in (2) gives :-
a + 38⅓ = 123, a = 123 - 38⅓ = 84⅔.
So, a = 84⅔ and b = 38⅓

The sum of three numbers is 105. The third number is 11 less than 10 times the second. Twice the first is 7 more than 3 times the second. Find the numbers.?
a=58.4615 b=5.2308 c=41.3076
The sum of two numbers is seventy-five the second number is three less than twice the first find the numbers?
Let x represent the first number; 2x - 3 then represents the second number. x + 2x - 3 = 75 3x = 78 x = 26 2x - 3 = 49 So the numbers are 26 and 49.
The sum of three numbers is 26 The second number is twice the first and the third number is 6 more than the second Find the numbers?
Number one = x Number two = y Number three = z x + y + z = 26The second number is twice the first. y = 2x The third number is 6 more than the second. z = y + 6 z = 2x + 6 x + 2x + (2x + 6) = 26 5x = 20 x = 4 Number one = 4 Number two = 8 Number three = 14
How do you find the LCM of 2 numbers if one number is prime?
If the second number is a multiple of the prime number, than the LCM is the second number. If the second number is not a multiple of the prime number, then the two numbers are relatively prime, and the LCM is the product of the two numbers.
