Sagot :

Answer:

[tex]x=7[/tex]

Step-by-step explanation:

First, add like terms. In this case, you would add [tex]8[/tex] to both side to get rid of it from the left side, and with its like term, [tex]20[/tex].

[tex]4x-8=20→4x=28[/tex]

Then, divide both side by 4 to isolate [tex]x[/tex].

[tex]4x=28→x=7[/tex]

The answer is [tex]x=7[/tex].

The answer is X = 7
