One number is 14 less than the other if there sum is increased by seven the result is 85. find the numbers

32 and 46.

Step-by-step explanation:

y = x - 14

x + y  + 7 = 85

x + y = 78

From the first equation:

-x + y = -14    Adding the last 2 equations:

2y = 64

y = 32

and  from the first equation (y = x - 14) :

32 = x - 14

x = 32 + 14 = 46.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
