if y=3x+7
how do you finish the ttable for linear equation?
X y
3 blank
blank 4

DrBob222,
The only t table I know about is the statistical t and that doesn't fit a prealgebra problem. So I assume you mean to substitute 3 for x and you want to know y. Then substitute 4 for y and you want to know x.
If so,
y = 3x+7
y = 3(3)+7
y = 9+7
y = 2
etc. Check my work.
