Question

find the value of x, y, and z, in the rhombus below.
answer
attempt 1 out of 2
x =
y =
z =

Explanation:

Step1: Set equal sides for x

All sides of a rhombus are equal, so $-3x - 3 = 9$.
Solve: $-3x = 12 \Rightarrow x = -4$.

Step2: Set equal sides for y

All sides of a rhombus are equal, so $8y - 7 = 9$.
Solve: $8y = 16 \Rightarrow y = 2$.

Step3: Set equal sides for z

All sides of a rhombus are equal, so $-2z + 5 = 9$.
Solve: $-2z = 4 \Rightarrow z = -2$.

Answer:

$x = -4$
$y = 2$
$z = -2$
