Question

slove
2x—4=8
pls help me​

Answer 1

Answer:

x = 6.

Step-by-step explanation:

You want to isolate x, so do as much as possible.

2x - 4 + 4 (to remove 4 on this side) = 8 + 4

Why do you need to do it on the other side? Since there is an equal sign, what you do on one side must be done on the other.

2x = 12 (8 + 4).

Now you want to eliminate the 2 from 2x so you have x.

In this sense, you want to make it 1x, so divide by 2 (2x is x times 2).

2x/2 = 12/2.

1x = 6.

x = 6.
