one Solve for the unknown prob

Please help. I don't remeber were to start on this one.
Usually after the first step I've pretty much got it.


42 = 7t - 42

Rearrange it so you have the t isolated.

42 = 7t - 42
42 + 42 = 7t
84 = 7t
84 / 7 = t
12 = t

42 = 7t - 42
42 + 42 = 7t
84 = 7t
84 / 7 = t
12 = t

I see.

42 + 42 = 84 : 7 = 12

I see.
42 + 42 = 84 : 7 = 12

You "see" 7 = 12? What do you mean?
