490
1 x 98, 2 x 49, 7 x 14 = 98
If: -14x = -98 Then: x = 7
65x = 104 x = 104/65 = 8/5 or 1 and 3/5
These formulas fit that criteria: 7 x 14 = 98 2 x 49 = 98 1 x 98 = 98
This one looks like No Solution. This is how I read it: 5x = 8 = 98-4x. If 5x = 8, then x = 8/5 = 1 3/5 (or 1.6), substitute into 98 - 4x --> 98 - 4(1.6) = 91.6, which does not equal 8, as it should from the equation.
49 x 10 = 490 7 x 70 = 490 98 x 5 = 490 2 x 245 = 490
For example: 2*49 = 98
98 x 5 = 490
x=6=x=5+x=13+x=20 x cannot = x+5. This question has no answer.
77 x 98 = 77 x (100 - 2) = 7700 - 154 = 7546
1 x 98, 2 x 49, 7 x 14, 14 x 7, 49 x 2, 98 x 1 = 98
x/7 = 14 x = 98
