Note: If there are no solutions, write "No Solution" or "None" for each answer. If there are infinitely many solutions, and the solution set
describes a line (that is, if there is only one free variable), set x2 = t and solve for the remaining variables in terms of t. If there are infinitely many
solutions, and the solution set describes a plane (that is, if the solution set has two free variables), set the variables *3 = t and x₂ = s, and then
solve for ₁ in terms of s and t.
