Respuesta :
8x+4= 20
move +4 to the other side
sign changes from +4 to -4
8x+4-4= 20-4
8x= 20-4
8x= 16
divide both sides by 8 to get x by itself
8x/8= 16/8
Cross out 8 and 8, divide by 8 and then becomes 1*1*x= x
x= 16/8
Answer: D. x = 2
In order to get the answer to this question you will have to solve the equation before you can get the answer.
[tex]8x+4=20[/tex]
[tex]-4-4[/tex]
[tex]20-4=16[/tex]
[tex]8x=16[/tex]
[tex]\div8\div8[/tex]
[tex]16\div8=2[/tex]
[tex]x=2[/tex]
Therefore your answer is option D "x = 2."
Hope this helps.
