If: 3x+7 = 19
Then: 3x = 19-7
And: 3x = 12
So: x = 12/3 = 4
It is 17 because (17+19)/3 = 12
the answer is 9
the number is 11
The number 378 can be expressed as a sum of its prime factors: (378 = 2 \times 3^3 \times 7). It is also an even number, making it divisible by 2, and is the sum of the squares of two integers: (378 = 19^2 + 17^2). Additionally, in Roman numerals, it is represented as CCCLXXVIII.
19 + 3 = 22
Reverse the operations. Start with 19, subtract 4, which leaves 15. Divide 15 by 3, and that is the number you began with.
It is 17 because (17+19)/3 = 12
5x + 6
The numbers are 19 and 5
the answer is 9
3 + 23 7 + 19 13 + 13
what is 4 times the sum of a number squared and 3
19 and 3; 17 and 5.
10n = -30 n = -3
the number is 11
-3
That number would be 3
