Solutions 

In Matrix we use initially based on systems of linear equations.The matrix method is similar to the method of Elimination as but is a lot cleaner than the elimination method.Solving systems of equations by Matrix Method involves expressing the system of equations in form of a matrix and then reducing that matrix into what is known as Row Echelon Form.<span> 

Calculations </span>

⇒ <span>Rewrite the linear equations above as a matrix 

</span>\left[\begin{array}{ccc}7&-4&13\\2&-5&-4\\\end{array}\right] 

⇒  Apply to Row₂ : Row₂ - 2/7 <span>Row₁ 
</span>
\left[\begin{array}{ccc}7&-4&13\\0&-27/7&-54/7\\\end{array}\right] 

⇒ <span>Simplify rows 
</span>
\left[\begin{array}{ccc}7&-4&13\\0&1&2\\\end{array}\right] 

Note: The matrix is now in echelon form.
<span>The steps below are for back substitution. 
</span>
⇒ Apply to Row₁ : Row₁ + 4 Row₂ 

\left[\begin{array}{ccc}7&0&21\\0&1&2\\\end{array}\right]

⇒ <span>Simplify rows
