Answer 1

1. variable by itself with a coefficient of 1 on one side of the equation and all the other variables and constants on the other side.

2.Because solving an equation is to find its solutions, which are the values (numbers, functions, sets, etc.) that fulfill the condition stated by the equation, consisting generally of two expressions related by an equals sign. When seeking a solution, one or more variables are designated as unknowns.
