Option a: [tex]56+8 x=80[/tex]
Option d: [tex]2 x=6[/tex]
Option e: [tex]x=3[/tex]
Explanation:
The expression is [tex]\frac{1}{4}(8 x+56)=20[/tex]
simplifying, we have,
[tex]8x+56=80[/tex]
Subtracting,
[tex]8x=24[/tex]
Dividing, both sides by 8, we have,
[tex]x=3[/tex]
Option a: [tex]56+8 x=80[/tex]
Solving we have,
[tex]8x+56=80[/tex]
Subtracting,
[tex]8x=24[/tex]
Dividing, both sides by 8, we have,
[tex]x=3[/tex]
Hence, Option a is the correct answer.
Option b: [tex]19=20-8 x[/tex]
Solving,
[tex]-1=-8x[/tex]
Dividing, both sides by -8, we have,
[tex]x=\frac{1}{8}[/tex]
Hence, Option b is not the correct answer.
Option c: [tex]2 x+14=5[/tex]
Simplifying,
[tex]2x=-11\\x=-\frac{11}{2}[/tex]
Hence, Option c is not the correct answer.
Option d: [tex]2 x=6[/tex]
Dividing, both sides by 2, we have,
[tex]x=3[/tex]
Hence, Option d is the correct answer.
Option e: [tex]x=3[/tex]
Hence, Option e is the correct answer.
