2x + 6 = ?
what is the answer for this question?
Who knows? We can't find the value of x until
we know what the expression equals. Plug in
different values on the right side, and you
will get different values for x.
Examples:
2x + 6 = 14 x = 4
2x + 6 = 0 x = -3
2x + 6 = 37 x = 15.5
2x + 6 = -18 x = -12
2x + 6 = 54 x = 24
2x + 6 = -126.781 x = -66.3905
Give us something to work with.
