Answer:
x = 8, y = 2
Step-by-step explanation:
2x - 7y = 2 (1)
4x + 5y = 42 (2)
2x = 2 + 7y (1)
2(2 + 7y) + 5y = 42 (2)
4 + 14y + 5y = 42
19y = 38
y = 2
2x = 2 + 7(2) = 16
x = 8

<h2>
Explanation:</h2>
In this exercise, we have the following point:
Let's assume that y varies directly as x, so this implies we can writ y as the product of x and some non-zero real constant k. In a mathematical language:
As you can see, this is the equation of a line whose slope is k and passes through the origin. Therefore, the slope of the line is the constant of proportionality we are looking for:
