Solve the following equation. x + 6 = x + x 2 6 14 72 the correct answer is 72. i just need someone to show the work, .

x=6

Step-by-step explanation:

x + 6 = x + x        original problem

x + 6 = 2x            combine like terms

-x      = -x             subtract x from both sides to have like terms on each side

6 = x                    solution

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
