9x - 10y = -34
3x - 4y = -16

Answer 1

Hi there!

I believe your answer is:

(4,7)

Here’s why:

• I have graphed the system on a program.
• The two lines intercept at the point (4,7). This means that it is the solution to the system.
• See the graph attached.

Hope this helps you. I apologize if it’s incorrect.

Answer 2

`9x - 10y = - 34 - - - (a) \\ 3x - 4y = - 16 - - - (b) \\ (a) - 3 * (b) : \\ 0x + 2y = 14 \\ y = 7 \\ 3x - (4 * 7) = - 16 \\ 3x = 12 \\ x = 4`

answer: ( 4, 7 )
