Two Mechanics Worked On A Car

Two mechanics are working on a car. Does the first mechanic work 10 hours and the second mechanic 15 hours? 3

Two mechanics are working on a car. The first mechanic worked 10 hours and the second mechanic worked 15 hours. Together they charged a total of $ 150. If the two fees combined were $ 165 per person, how much did each mechanic charge per person?

10x + 15 years = 1950

x + y = 165

Solution for X.

x = 165 years

Alternatives

10 (165 years) + 15 years = 1950

1650 10 years + 15 years = 1950

5 years = 300

y = 60

Connect to x:

x = 16560

x = 105

The first mechanic earns $ 105 per hour.

Another mechanic earns $ 60 an hour.

Two Mechanics Worked On A Car

Here you need two equations.
Allows you to use the first engine as A and the second as B.
now
10A + 15B = 1950
A + B = 165
A = 165 B
Use alternatives
10 (165B) + 15B = 1950
1650 10B + 15B = 1950
10B + 15B = 1950 1650
5B = 300
B = 300/5
B = $ 60
now
A = 165 B
A = 165 60
A = $ 105
That should be fine, please.
20x + 5y = 2,550 $ x + y = 195 $ yyx = 195 $ y (replace x) 20 (195 $ y) + 5y = 2,550 $ 3,900 $ 20y + 5y = 2,550 $ 3,900 $ 5, $ 1 y = 3,900 $ 5, 90 3 90 $ (change and delete y) 20x + 5 (90) = 2550 $ 20x + 450 = 2550 $ 20x = 2100 $ x = one dred and five $ Answer: x = one dred and five after ur, y = 90 is suitable for you
