You can think of the action of multiplying matrix <em>A</em> onto any other matrix <em>X</em> as
• preserving the first row of <em>X</em> due to the +1 in the first column of the first row,
• negating the second row of <em>X</em> due to the -1 in the second column of the second row, and
• preserving the third row of <em>X</em> due to the +1 in the third column of the third row.
Step-by-step explanation:

Hi there!
If the lines are parallel, Angles 1 and 2 would have to be congruent because they are corresponding angles. Therefore, to solve, all we need to do is set the values of the angles equal to each other because the angles are congruent.
WORK:
20 - 8x = 30 - 16x
-8x = 10 - 16x
8x = 10
x = 1.25
Hope this helps!! :)
