A Rhombus has four equal straight sides. We can assume that the rhombus in this problem is square-shaped with 90° angles.
m1 = 18x ; 90 = 18x ; 90/18 = x ; 5 = x
m2 = x + y ; 90 = 5 + y ; 90 - 5 = y ; 85 = y
m3 = 30z ; 90 = 30z ; 90/30 = z ; 3 = z
x = 5 ; y = 85 ; z = 3
x + y + z ⇒ 5 + 85 + 3 = 93
X-y=7
so you have to rewrite the equation in the form of mx+b=y
so ... x-y=7
-x -x
-y=7-x then simplify
-y(-y)=-(7-x) multiply both sides by -1
y=-7+x
which is the same y= x-7
y=x+-7

Step-by-step explanation:
(k-p)(k-n)
=k^2 -(p+n)k+pn
this is the expanded form..
