Mathematics

see explanation

Step-by-step explanation:

4G - 6H

= 4 $\left[\begin{array}{ccc}1&-7\\7&6\\\end{array}\right]$ - 6 $\left[\begin{array}{ccc}1&1\\-3&7\\\end{array}\right]$ ← multiply each component by the scalar

= $\left[\begin{array}{ccc}4&-28\\28&24\\\end{array}\right]$ - $\left[\begin{array}{ccc}6&6\\-18&42\\\end{array}\right]$ ← subtract corresponding components

= $\left[\begin{array}{ccc}4-6&-28-6\\28-(-18)&24-42\\\end{array}\right]$

= $\left[\begin{array}{ccc}-2&-34\\46&-18\\\end{array}\right]$
