Answer:
First mechanic worked 20 hours and second mechanic worked 5 hours
Step-by-step explanation:
Let the number of hours the first mechanic worked = ![a](https://tex.z-dn.net/?f=a)
Let the number of hours the second mechanic worked = ![b](https://tex.z-dn.net/?f=b)
Therefore, we can write 2 equations and then solve them simultaneously:
![a+b=25](https://tex.z-dn.net/?f=a%2Bb%3D25)
![65a+90b=1750](https://tex.z-dn.net/?f=65a%2B90b%3D1750)
Rearranging the first equation: ![a=25-b](https://tex.z-dn.net/?f=a%3D25-b)
and substituting into the second equation to find
:
![65(25-b)+90b=1750](https://tex.z-dn.net/?f=65%2825-b%29%2B90b%3D1750)
![1625-65b+90b=1750\\ 25b=125\\ b=5](https://tex.z-dn.net/?f=1625-65b%2B90b%3D1750%5C%5C%0A25b%3D125%5C%5C%0Ab%3D5)
Now sub
into the first equation to find ![a](https://tex.z-dn.net/?f=a)
![a+5=25\\ a=20](https://tex.z-dn.net/?f=a%2B5%3D25%5C%5C%0Aa%3D20)
Therefore, first mechanic (a) worked 20 hours and second mechanic (b) worked 5 hours
