-2z - xy = z + 7
You are solving for x. Note the equal sign. What you do to one side, you do to the other. Isolate the x.
First, add 2z to both sides
-2z (+2z) - xy = z + 7 (+2z)
Simplify. Combine like terms
-xy = z + 2z + 7
-xy = 3z + 7
Completely isolate the x. Divide -y from both sides
(-xy)/-y = (3z + 7)/-y
x = (3z + 7)/-y
Simplify
z = (3z + 7)/(-y) is your answer
hope this helps

Answer:
a=7.14yd
Step-by-step explanation:
process same as in above question
The best arrangement can be
- 3 rows and 4balls each row
So
- Length of one row=1.8(4)=7.2cm
- Width=1.8(3)=5.4cm
- Height=1.8(2)=3.6cm
So
TSA
- 2(LB+BH+LH)
- 2(5.4(7.2)+(7.2)(3.6)+3.6(5.4))
- 2(84.24)
- 168.48cm²
Total cost
Answer:
it must always have one of the sign
