Solving equations with unknown in both sides
Given, 8x - 8 = 2x + 10
Solution: To solve this kind of problem, the first step is to always collect the like terms together i.e. Take the terms with x to one side of the equal sign and the numbers to the other side.
Recall: When terms cross the equal sign, their sign (+ or -) changes.
8x - 8 = 2x + 10
8x - 2x = 10 + 8
6x = 18
Now divide both sides by 6
6x/6 = 18/6
x = 3.
So always remember, collect like terms, simplify and then solve for the unknown.

A curve is mapped by the equation y = 3x^3 + ax^2 + bx, where a is a constant. The value of dy/dx at x = 2 is double that of dy/dx at x = 1. A turning point occurs when x = -1. Find the values of a and b.
