Step-by-step explanation:

x + 4 = 2x + 1

-x        -x

4 = 1x + 1

-1          -1

3 = 1x

--    --

1      1

3 = x

Check:

3 + 4 = 2(3) + 1

7 = 6 + 1

7 = 7

Answer:

x=3

Step-by-step 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 :))
