When you 'solve' an equation, what you wind up with is the value for 'x' that makes
the equation a true statement. When you write the solution down on paper, it says:
"X equals ...".
There's no question, puzzle, riddle, or mystery in your question. Nothing about it is
unknown. In fact, it's not a question at all. It's a statement. It tells us that "X is the
number 2."
Your "question" looks exactly like a solution, and there's nothing to it that needs solving.
The answer is x = 2.
-21
To solve x + 1.4 = 2, subtract 1.4 from each side; x = 0.6
7
x-2 = 14 x = 14+2 x = 16
The answer is x = 2.
x=-2

-21
To solve x + 1.4 = 2, subtract 1.4 from each side; x = 0.6
7
x-2 = 14 x = 14+2 x = 16
log9(x)=2 x=9^2 x=81
First, solve for y.y=-8xif x=2, then y=-16.
x=2
Suppose x3-4x = 0. To solve, factor: x3-4x = x(x2-4) = x(x+2)(x-2) = 0 Now, a product equals 0 if and only one or more of the factors equals 0, so set each factor to 0 and solve. The roots are 0,-2 and +2.
You would take 2 and replace it for x in your other equation and solve.
