Solve x2 - 14x + 31 = 63 for x.

When solving for a variable, you get that variable on one side and everything to the opposite of the variable you are trying to solve.

We have the equation 2x - 14x + 31 = 63.

First, combine like terms. We can add 2x to - 14x because they both have the variables.

2x - 14x + 31 = 63 becomes - 12x + 31 = 63

Now get rid of the 31 on the left side. To do this, subtract 31 from each side of the equation.

-12x + (31 - 31) = 63 - 31 =

-12x = 32

Then divide by the coefficient of - 12x. Which is - 12.

-12x / - 12 = 32 / - 12 =

x = - (2/3)

So, - 2/3 is the answer to this question.
