7-4x= 31
Bring over 7 to the other side
Positive 7 changes into negative 7
7-7-4x= 31-7
-4x= 24
Divide by -4 for -4x and 24
-4x/-4= 24/-4
x= -6
Check answer by using substitution method
7-4x= 31
7-4(-6)= 31
7+24= 31
31= 31

The distance he has traveled vertically to the nearest yard in combined trip is 111 yards.
<em><u>Solution:</u></em>
Given that,
Each step is 8 inches high
There are a total of 50 stairs
So the height of 50 stairs is:
Height of 50 stairs = 50 x 8 = 400 inches
Joseph makes 10 round trips up and down the stairs
So, joseph has went up 10 times and he came down 10 times
We need to find the distance he has traveled vertically in the combined trips
Therefore,
Number of times he went up = 10
We know that,
height of 50 stairs = 400 inches
Therefore,
Distance traveled up = 10 x 400 = 4000 inches
Convert to yard
1 yard = 36 inch
Therefore,

Therefore, the distance he has traveled vertically to the nearest yard in combined trip is 111 yards
