Question 122373: I need to solve with a system of linear equations and I don't know how to write the equation.
The new parking lot has spaces for 450 cars. The ratio of spaces for full-sized cars to compact cars is 11 to 4. How many spaces are for full-sized cars? How many spaces are for compact cars?
I just need the equation. thanks!

The new parking lot has spaces for 450 cars. The ratio of spaces for full-sized cars to compact cars is 11 to 4. How many spaces are for full-sized cars? How many spaces are for compact cars?
:
Let x = no. of spaces for full size cars
then
(450-x) = no. of spaces for compact cars
:
"The ratio of spaces for full-sized cars to compact cars is 11 to 4."
x%2F%28%28450-x%29%29 = 11%2F4
:
You can cross multiply to solve this:
