This year the parking lot should have 16 spaces for RVs

Step-by-step explanation:

we know that

using proportion

solve for r

Multiply in cross

therefore

This year the parking lot should have 16 spaces for RVs

x ----> the number of car spaces

r ----> the number of RV spaces

we know that

----> equation A

----> equation B

substitute equation A in equation B

solve for r

\

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
