I don’t think it would work it you solved for k instead of y. Because you’re solving for y when you do constant of proportionality. i’m not sure if i’m right or not but that’s what i think.

Answer:
x = 82
y = 98
z = 87
Step-by-step explanation:
By inscribed angle theorem:
x° and y° are the measures of the opposite angles of a cyclic quadrilateral.
Opposite angles of a parallelogram are supplementary.
Therefore,
x° + y° = 180°
82° + y° = 180°
y° = 180° - 82°
y° = 98°
y = 98
Similarly,
93° + z° = 180°
z° = 180° - 93°
z° = 87°
z = 87
Answer:
780
Step-by-step explanation:
Let x be the original price
x - x*72% is the new price
x - .72x = 218.40
.28x = 218.40
Divide each side by .28
.28x/.28 = 218.40/.28
x =780
It is a linear equation with only one unknown, although it looks strange because of the fractions, so lets get rid of the fractions:
<span>2/x = 1/4
</span>(2/x) = (<span>1/4)
</span>4*(2/x) = <span>1
8/x = 1
8 = 1*x
x = 8
that is the solution</span>
