To find the sum of two and one third plus five sixths of one and two fifths, first convert all the mixed numbers to improper fractions. Two and one third is equivalent to 7/3, one and two fifths is equivalent to 7/5. Next, find five sixths of 7/5 which is 35/30 or 7/6. Finally, add 7/3 and 7/6 to get 21/6 + 7/6 = 28/6 which simplifies to 4 and 2/6 or 4 and 1/3. Therefore, the sum is 4 and 1/3.
6 x (7 - 2) + 1 = 31
1/3 x 6/7 = 6/21 = 2/7 The reciprocal is 7/2 1/3 x 7/6 = 7/18 The reciprocal is 18/7
X/7 = 6 multiply both sides by 7/1 (7/1)(X/7) = (6)(7/1) 7 cancels on left X = 42 ----------------check in original equation 42/7 = 6 6 = 6 ----------checks

Expanded Notation of 617 = (6 x 102) + (1 x 101) + (7 x 100) OR (6 x 100) + (1 x 10) + (7 x 1).
-6x = 7 x = 7 / -6 x = (-7/6), i.e. -1 1/6, i.e., negative one and one sixth.
7=x+1 6=x
if you mean (x-5)/6=1/3 then x=7 but if you mean x-(5/6)=1/3 then x=1 1/6 or 7/6
It is 1.....7 x 4 (-3 from 7)...x...2 (-2 from 4) .... x... 1 (-1 from 1)....x....1 (-0 from 1)...then x. x=6 in this case, but it could be any number whatsoever which is why i have termed it x. Btw, what do you need this for? Cheating an IQ test?
7 x 1?
If you mean: 6 = x-1 then the value of x is 7
logx +7=1+log(x-1) 6=log(x-1)-logx 6=log[(x-1)/x] 10^6=(x-1)/x 1,000,000x=x-1 999,999x=-1 x=-1/999,999
if is (x-6)-(1x-1) = -5 if id (x-6)-(1x+1) = -7
The equation would be x + 6. 1 + 6 = 7 2 + 6 = 8
