Question

Need help with finding out what X is?

Answer 1

x=3

Explanation:

x + 4 = 2x + 1

subtract 1 from both sides

4 = 1x + 1

you wanna subtract 1 from both sides

3 = 1x

now you wanna divide 1 from both sides to get x by itself

3 = x

since you cannot write a equation like that you wanna swap it

x=3

hope that helped :))
