Answer:

(9,4)

Explanation:

The given system is:

9x + 3y = 93

3x - 4y = 11

Multiply the bottom equation by 3 to get:

9x + 3y = 93

9x - 12y = 33

Subtract bottom equation from top one to get:

3y--12y=93-33


15y = 60


y = (60)/(15)


y = 4

We put y-value into the bottom equation:


3x - 4 *4= 11


3x - 16= 11


3x = 11 + 15


3x = 27


x = (27)/(3)


x = 9
