9w + 8x +9y + 2z = 42 6w + 4x + 3y + 6z = 53 8w + 2x + 5y + 62 = 63 5w + 2x + 7y + 3z = 45
Added by Juan Luis J.
Step 1
\(9w + 8x + 9y + 2z = 42\) 2. \(6w + 4x + 3y + 6z = 53\) 3. \(8w + 2x + 5y + 62 = 63\) 4. \(5w + 2x + 7y + 3z = 45\) we will use the method of elimination or substitution. Let's proceed step by step. ** Show more…
