Answer:
Below in bold.
Step-by-step explanation:
As we all know a car has 4 wheels and a motorcycle has 2 so we can write 2 equations:
x + y = 140 where x = number of cars and y = number of cycles.
4x + 2y = 370.............A
Multiply first equation by 2:-
2x + 2y = 280.............B
Subtract equation B from A:
2x = 90
x = 45.
So there are 45 cars and 140 - 45 = 95 motorcycles.

Answer:
Step-by-step explanation:
if it's
23 = 5 - (2/3)m
18 = (-2/3)m
m = 18(-3/2)
m = -27
if it's
23 = 5 - 2/(3m)
18 = -2/(3m)
18(3m) = -2
54m = - 2
m = -2/54
m = - 1/27
