let's see:
2 - 7x = 65
2 - 7(-9) = 65
negative times negative = positive
2 +(7 * 9 = 63) = 65
2 + 63 = 65
65 = 65
True that -9 is a solution

yes.
2 - 7x = 65
-7x = 65 -2
-7x = 63
x = 63:-7
x = -9
Solution: {x element of R | x = -9}

ya, It looks like it would be that.
2 - 7(-9) = 2 - (-63) = 2 + 63 = 65
Yes, it appears -9 = x
