C. x = 5
Step-by-step explanation:
x + 3 = 3x - 7
Add -3x and -3 on both sides.
x - 3x = -7 -3
Add or subtract like terms.
-2x = -10
Multiply -1 on both sides.
2x = 10
Divide 2 into both sides.
2x/2 = 10/2
x = 5
Answer:

Step-by-step explanation:
4-xy=y^3
dy/dx=?

Solving for dy/dx: Addind x dy/dx both sides of the equation:

Common factor dy/dx on the right side of the equation:

Dividing both sides of the equation by 3y^2+x:

Answer:
Q ' (3,4)
Step-by-step explanation:
