You pass the free terms wich don't contain 'x' in the othe part of the equal with changed signe ans the same for the terms wich contain x.
The value of y is equal to 18.
<h3>What is the value of a variable related to geometric system?</h3>
In this problem we have a geometric system generated by two lines intersecting each other and generating two pairs of angles supplementary to each other. The system of linear equations representing the situation is presented below:
(8 · y - 13) + (3 · x + 4) = 180
3 · x + 8 · y = 189 (1)
(10 · x - 19) + (3 · x + 4) = 180
13 · x = 195 (2)
The solution to this system is (x, y) = (15, 18). The value of y is equal to 18.
