Let
x----------> the first mechanic rates
y----------> the second mechanic rates
we know that
x+y=165
15x+5y=1775
using a graph tool
see the attached figure
the solution is
x=95
y=70
the answer is
the rates of the first mechanic is 95the rates of the second mechanic is 70
The slope of the graph is -1/2 using the rise over run method it rises up one and too the left twice so it would he -1/2
Step-by-step explanation:
22x+7= -15
22x= -15 -7
22x = -22
x= <u>-</u><u>2</u><u>2</u>
22
x= -1
Hope this helps you dear !
Have a great day :)
