Answer:

D. (6,6)

Step-by-step explanation:

Given the system of two equations

\left\{\begin{array}{l}3x+5y=48\\ \\-3x+5y=12\end{array}\right.

1. Add these two equations:

3x+5y-3x+5y=48+12\\ \\10y=60\\ \\y=6

2. Subtract these two equations:

(3x+5y)-(-3x-5y)=48-12\\ \\3x+5y+3x-5y=36\\ \\6x=36\\ \\x=6

Hence, the solution to the system is (6,6)
