Answer:
38=7x-y
Step-by-step explanation:
standard form= Ax+By+C
(y-3=7(x-5))
(y-3=7x-35)+3 to both sides
(y=7x-38) +38 to both sides
(y+38=7x) -y to both sides
38=7x-y
you have to move the 38 and y because if you moved the x value, than A becomes negative and it can't be in standard form
Working together three workers would take 1 hour 36 minutes to finish the job
<em><u>Solution:</u></em>
Given that first worker can finish the job in 8 hours
