Answer:
x=-8z/5 - 3y/5
Step-by-step explanation:
distributive prop
3x-3y=8x+8z
isolate x by moving 8x to the left, and -3y to the right
-5x=3y+8z
divide by -5 on both sides.
x=-8z/5 - 3y/5

Answer:
A. y = -14
Step-by-step explanation:
The phrase “ y varies inversely as x” or “ y is inversely proportional to x” means that as x gets bigger, y gets smaller, or vice versa. This concept is translated in two ways. yx = k for some constant k, called the constant of proportionality, or y = k/x (they are essentially identical though.)
Thus, from given information, we first need to find that constant k to be able to solve for either y or x in the future
y * x = k
7 * (-4) = k
k = -28
Now, we can find what y equals when x = 2:
y * x = k
y * (2) = -28
y = -28/2
y = -14
