10x - 8y = -2
9x + 8y = 59

A. (7, 9)
B. (7, 8)
C. (3, 3)
D. (3, 4)

Answer 1

This time, can you solve it for me?

Answer 2

well i solved it and got b

Answer 3

\(\Large \color{purple}{\rightarrow 19x = 57 }\)
\(\Large \color{purple}{\rightarrow x = 3 }\)

Now, solve this equation:

\(\Large \color{purple}{\rightarrow 27 + 8y = 59 }\)
\(\Large \color{purple}{\rightarrow 8y = 32 }\)
\(\Large \color{purple}{\rightarrow y = 4 }\)

(3,4)

Answer 4
