YOUR ANSWER IS (-18,9)
skelet666 [1.2K]3 years ago
5 0

Answer:

90/13, 45/13

Step-by-step explanation:

- 2 = x \\ 7x + 9y =  - 45 \\  \\ 7 \times ( - 2)y + 9y =  - 45 \\ y = 9 \\  \\ 7x + 9 \times 9 =  - 45 \\ x =  - 18 \\ (x.y) =  (- 18.9) \\  \\

Simplify:

- 2 \times 9 =  - 18 \\  7 \times ( - 18) + 9  \times 9 =  - 45 \\  - 18 =  - 18 \\  - 45 =  - 45

just multiply your decimal by 100 to get a percent which is easier to see which is bigger.
