2x+7=9 what does x equal and how did you solve for it?
This is a very easy question. The value of x is easy to find because that is the only unknown option. If there had been more than one unknown option, then it would have been difficult to solve, at least more difficult than the given situation. The equation that is given is: 2x + 7 = 9 2x = 9 -7 2x = 2 x = 2/2 = 1 So the value of x is 1 as can be found by deducing the given equation in the question.
-- Subtract 7 ftom each side. -- Divide each side by 2.
