If 3x - 1 = 11: To solve this equation, add 1 to each side of the equation to isolate x (3x -1 +1 = 11 + 1) and now the equation is 3x = 12. The next step is to divide both sides of the equation by 3 to find the value of x (3x / 3 = 12 / 3) for the answer x = 4. Not sure what you mean by x2 x, but you can substitute the value of x (which is 4) to solve.

- If 3X - 1 = 11, what is the value of X^2 + X?
3x-1 = 11 3x = 11+1 3x = 12 x = 4 Therefore: x2+2 = 18
3x-1 = 11 3x = 11+1 = 12 x = 12/3 = 4 Therefore: x2 + 2 = 16 + 2 = 18
The vertex has a minimum value of (-4, -11)
