Linear equation in one variable has (a) only one variable with any power. (b) only one term with a variable. (c) only one variable with power 1. (d) only constant term. To solve equations like 5t = –20, you still need to get the variable t, on its own. The variable has been multiplied by a number, 5 — so you can get the
