... Example 1A: Solving Linear Systems by Substitution Use variable substitution to solve the system: y= x–1 x+y=7 Step 1: Substitute the equivalent expression for “y” from the first equation in place of “y” in the second equation and solve for “x”. x+y=7 x + (x – 1) = 7 2x – 1 = 7 2x = 8 x=4 ...

... System of equations • These situations are called linear dependence: – Given vectors: x1, x2,…, xn-1 – Another vector xn is linearly dependent if there exists constants α1, α2,…, αn-1 such that: xn= α1x1+α2x2+ …+αn-1xn-1 • Otherwise the vector xn is linearly independent. • In case of linear depende ...
