For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
Doing the multiplication we have:

From here, we clear the value of x.
We have then:

Therefore, we have:
Answer:
7 times 1/7 equals 1

Answer:
w=-1.16u
Step-by-step explanation:
first you want to put the W's on one side and the U's on the other. we can do this by subtracting 4u from the left side and the right side making the equations 8w=-7u+2w.
next we want to subtract 2w from both sides making the equation 6w=-7u then we divide by 6 to get w=-1.16u
The answer to this is 384.57909
Answer:
B
u just subsitute in each inequality form and so u will find the only one that is right is letter b
-4 is x
-2 is y
