This is the existence of additive inverse: For every number, x, there exists a number, denoted by (-x), such that x + (-x) = (-x) + x = 0.

69 = 1 x 69 69 = 3 x 23
1 x 69, 3 x 23 = 69
1 x 69, 3 x 23 = 69
15 x 69 = 1035
1 x 69, 3 x 23, 23 x 3, 69 x 1.
69 = 18/100 * x x = 69*100/18 x = 1150/3 ~= 383.33
Since 69 is a factor of 207, it will automatically be the GCF of this problem. But let's do it correctly. 3 x 23 = 69 3 x 3 x 23 = 207 Select the common factors. 3 x 23 = 69, the GCF.
The answer is 3. 69/X=23 69/23=X=3
