You can put this solution on YOUR website!
y+=+x+%2B+5 ?......let' check them all
a) when x is 7....->...y+=+7+%2B+5=12....true
b) (3,2) is a solution.....->...2+=+3+%2B+5..->...2+=+8..NOT true
c) when the independent variable is -1, the dependent variable is 4->...4+=+-1+%2B+5..->...4+=+4..true


d) the output is 6 for an input of 1...->...6+=+1+%2B+5..->...6+=+6..true

so, your answer is: b) (3,2) is a solution...it's NOT true
