Step-by-step explanation:
X= -2+3y
....
-2+3y-3y=-2
-2+3y+3y=16
.......
6y=18
...
y=3
x=7
Given,
x - 3y = -2
x + 3y = 16
so,
solve a equation of x and we got,
x = 3y - 2
now,
now, substitute the given x value into the equation x + 3y = 16 so we got,
(3y - 2) + 3y = 16
solve a equation to y so
y = 3
substitute the given y value into the x equation
so we got,
= x = 3×3 - 2
= x = 7
so x = 7 and y = 3
so option A is correct!
Proportional quantities can be described by the equation y = kx, where k is a constant ratio. You can tell that the relationship is directly proportional by looking at the graph.
So yes it does equal a proportional relationship.
