Answer:
a=a or infinite.
Step-by-step explanation:
[tex]6a+4=4+6a\\6a=6a\\a=a[/tex]
a is infinite.
In other words, a could be any value that the equation would still make sense.
Answer:
All real numbers make the equation true.
Step-by-step explanation:
Since the same thing is one both sides of the equation, any real number for a will make the equation true. If you were to try to solve for a:
[tex]6a+4=4+6a[/tex]
Subtract 4 from both sides
[tex]6a+4-4=4-4+6a\\6a=6a[/tex]
Subtract 6a from both sides
[tex]6a-6a=6a-6a\\0=0[/tex]
Thus, any number for a is true.
