How do you solve equations using Substitution.

Substitution is one of the methods for solving linear equations. It is a good choice if there is a variable with a coefficient of 1. This method involves solving one of the equations for a variable and then substituting that expression into another equation to solve for another variable. This will produce a single equation with one variable, which can then be solved algebraically.

1. 8 or -82. 14 or -143. -11, -3, 0, 7, 10
