Question

Can anyone check my work?Is it right? If it is wrong what is the correct answer and where did I go wrong?


`3y-2x=11 \\ y+2x=9 \\ \\ 1.)3y-2x=11 \\ y=9-2x \\ \\ 2.)3(9-2x)-2x=11 \\ \\3.) (27-6x)-2x=11 \\ 27-6x-2x=11 \\ 27-8x=11 \\ -8x=-16 \\ x=2 \\ \\ 4.)y+2x=9 \\ y=9-2x \\ y=9-2(2) \\ y=9-4 \\ y=5 \\ \\ x=2 \\ y=5`

Answer 1

The answer is correct and you can always check your answer by substituting you the values in the question,

y + 2x = 9


according to your answer


5+ 2(2) = 9

9 = 9 (the answer is correct)

Answer 2

Good job! Your answer is correct, and you would just put the final answer as
`\sf{(2,5)}`.

Good job again :)
