The equation written in standard form is 7x - y = 17
<span>The angles of the figure are complementary, that is, the sum between them is equal to 90º.
Solving:
54º + 4xº = 90º
4xº = 90 - 54º
4xº = 36º
</span>


<span>
We have:
54º + 4.xº = 90º
54º + 4.(9º) = 90º
54º + 36º = 90º
90º = 90º (TRUE)
Answer:
</span><span>
