3.2d - 4d = 2.3d + 3...simplify by combining like terms
-0.8d = 2.3d + 3....subtract 2.3d from both sides
-0.8d - 2.3d = 3 ...simplify again
-3.1d = 3...divide both sides by -3.1
d = 3/ -3.1
d = - 0.97
or
3.2d - 4d = 2.3d + 3....multiply the equation by 10, gets rid of the decimals
32d - 40d = 23d + 30....subtract 23d from both sides
32d - 40d - 23d = 30....simplify
-31d = 30...divide by -31
d = -30/31
d = - 0.97

Answer: 14
Step-by-step explanation:
Okay so it asks in all, which means morning distance + afternoon distance
We got the afternoon distance so now we have to find the morning one
it says the afternoon distance (6), is 25% less than the morning distance.
Which means the afternoon distance is 0.75 of the morning distance.
so 0.75x = 6, x = 6/0.75 = 8
Then you add 8 to 6 to get 14
