Answer:
y - x = - 2 b
Step-by-step explanation:
Given-
3 x + 2 y = 5 a + b...................(i)
4 x - 3 y = a + 7 b.....................(ii)
<em><u>Multiply by 3 and 2 in equation (i) & (ii) respectively-</u></em>
<em><u>Add equation (iii) & (iv)-</u></em>
9 x + 6 y = 15 a + 3 a...................(iii)
<u>8 x - 6 y = 2 a + 14 b</u> ...................(iv)
17 x = 17 a + 17 b
<u>x = a + b</u>
Put x = a + b in equation (i)-
<em>2 y = 5 a + b - 3 a - 3 b</em>
<em>2 y = 2 a - 2 b</em>
<u>y = a - b </u>
<em>∴ y - x = a - b - ( a + b )</em>
<em>y - x = a - b - a - b</em>
y - x = - 2 b
Answer:
$36
Step-by-step explanation:
Jim worked from 8am - 2 pm , which is 6 hours
Woody worked form 10am - 2pm, which is 4 hours
If we take the total time (4+6 = 10) and divide the amount they got, we have:
$60/10 = $6 per hour worked
Since Jim worked 6 hours, he will be paid 6 * 6 = $36
The rest, 60 - 36 = $24 would be paid to Woody (he worked less).
Jim's fair share of earning is $36
