Answer:

(9,4)

Step-by-step 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 =  \frac{60}{15}

y = 4

We put y-value into the bottom equation:

3x - 4 \times4= 11

3x - 16= 11

3x = 11 + 15

3x = 27

x =  \frac{27}{3}

x = 9
