Answer:
Option A [tex]56+8x=80[/tex]
Option D [tex]2x=6[/tex]
Step-by-step explanation:
we have
[tex]\frac{1}{4}(8x+56)=20[/tex]
Multiply by [tex]4[/tex] both sides
[tex]\frac{1}{4}(8x+56)*4=20*4[/tex]
[tex](8x+56)=80[/tex]
Subtract [tex]56[/tex] both sides
[tex]8x=80-56[/tex]
[tex]8x=24[/tex] -------> is equivalent to [tex]2x=6[/tex]
[tex]x=3[/tex]
