Question

Please please help me

Answer 1

Answer:

x=-43, y=-12, and z=85

Step-by-step explanation:

There is one characteristic of a rhombus that will help us in this question.  That is that the sides of a rhombus are all equal, and given that one of the sides is 88, then all of the sides are 88 and so by setting all of the expressions equal to 88, we will get the answer.  

Let's start with z:

$z+3=88\\z+3-3=88-3\\z=85$

Now for y:

$-7y+4=88\\-7y+4-4=88-4\\-7y=84\\-y=12\\y=-12$

That leaves us with x:

$-2x+2=88\\-2x+2-2=88-2\\-2x=86\\-x=43\\x=-43$
