Answer:

no( -2=x. )

explanation:

if x =2 as given

then, 2×2+4=0

4+4 =0

8=0

if we take -2 as x

then,2×-2+4=0

-4+4=0.

OR

as per to exams the correct following is {to be understandable I said that now this is how u should write.}[even u can write like how I written before it's Ur wish.]

You want to separate x from everything else like so:

2x-4=00

2x=4 When moving -4 to the other side you use its inverse operation so when it gets to the other side its positive

x=2 2 and x are linked together by multiplication. Dividing 2x by 2 = 1x x times 1 is x. So usually you wont see a one by a variable. (X is a variable, I remember that because the number could vary and be anything till I solve the problem) then you divide the other side by 2 because you cant just pull that extra two fram anywhere, its moving to the other side! 4/2=2 so x=2

To check it, simply put 2 in parentheses where x is

2(2)-4=00

4–4=00

00=00

my answer is correct because the equation is balanced.

x=2.
