Undo the subtraction of x-2=6

x = 8

Step-by-step explanation:

I am assuming that you want to solve for x.

Note the equal sign, what you do to one side, you do to the opposite side. Isolate the variable, x. Add 2 to both sides:

x - 2 (+2) = 6 (+2)

x = 6 + 2

x = 8

x = 8 is your answer.

solution x= 4

Step-by-step explanation: equations are same when you transfer all terms on left side.

X^2-8x +16 = 0. It is same as (x-4)² = 0 when X= 4
