Create your own two-step equation with All Real Numbers as the solution. Show the steps to solving the equation to prove the solution All Real Numbers.
My answer is:
-2(x + 3) = -2(x + 1) - 4
-2x-6 =-2x-2-4
-2x-6=-2x-6
-2x=-2x
x=-2x/-2
Is this right?
So, what you have is mostly correct. |dw:1351659038210:dw| Because we have the same expressions on both sides of the equation sign, x could be any real number, and the equation would render true.
Does that make sense?
The correct answer then, for this problem, would be "All Real Numbers". Additionally, your question states prove that the solution to the eqn is all real numbers.
