Question 1110784
x, time of first mechanic
y, time of second mechanic


{{{system(x+y=25,55x+80y=1750)}}}
Simplify and solve the system.

{{{system(x+y=25,11x+16y=350)}}}


{{{system(11x+11y=275,11x+16y=350)}}}


{{{(11x+16y)-(11x+11y)=350-275}}}

{{{5y=75}}}

{{{highlight(y=15)}}}--------the second mechanic
-
{{{x+y=25}}}
{{{x=25-y}}}
{{{x=25-15}}}
{{{highlight(x=10)}}}---------the first mechanic
