Answer: x=−5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−4−7x=31
−4+−7x=31
−7x−4=31
Step 2: Add 4 to both sides.
−7x−4+4=31+4
−7x=35
Step 3: Divide both sides by -7.
−7x
−7
=
35
−7
x=−5
Answer:
xy = 3
d/dt(xy) = d/dt(3)
ydx/dt + xdy/dt = 0
y = 3/x so substitute 3/5 for y, 5 for x, and 5 for dy/dt; and solve for dx/dt.
3/5(dx/dt) + 5(5) = 0
3/5(dx/dt) = -25
dx/dt = -125/3
