Ответ:
change the order, so the terms line up
20g+15m=300
g+m=17
multiply the second equation by 20, so the 20g and -20g can cancel out
20g+15m=300
-20g-20m=-340
solve the equation, then divide -5 to both sides to isolate the m
-5m=-40
m=8
substitute the value of m into one equation to find the other value
g+8=17
g=9
write them in ordered paired form
(9, 8)
