<em>Answer:</em>
<em>The solution is (5, −2)</em>
<em>Step-by-step explanation : </em>
<em>x + y = 3 => y = 3 - x</em>
<em> y = x - 7 } => </em>
<em>=> 3 - x = x - 7 => 3 + 7 = x + x => 2x = 10 => </em><em>x = 5</em>
<em />
<em>x + y = 3</em>
<em>5 + y = 3</em>
<em>y = 3 - 5</em>
<em>y = - 2</em>

Step-by-step explanation:
In mathematics, two varying quantities are said to be in a relation of proportionality, if they are multiplicatively connected to a constant; that is, when either their ratio or their product yields a constant. The value of this constant is called the coefficient of proportionality or proportionality constant.
Original points are:
x = (3, -1); y = (4,-4); z = (1,-2).
A reflection across the line y = 1 (a line parallel to the y-axis) will keep the same x-coordinates and will move the y-coordinate upward as many units above the line y = 1 as units are from the line y = 1 to the y-coordinate of the original point.
Distance of (3,-1) to the line y = 1 is 1 - (-1) = 2 => new y-coordinate = 1 + 2 = 3.

Answer:
Denote the cards he had when he started: a
=> 2 x a + 6 = 98
=> 2 x a = 92
=> a = 92/2 = 46
=> He started with 46 cards.
Hope this helps!

Answer:
This is a true statement. I think that's what you're asking.
Step-by-step explanation:
It is true because if x=y, than 6x=6y because both sides have a 6 and x=y
