Answer:
The value of the equation is [tex]a=\frac{c-4d-b}{2}[/tex].
Step-by-step explanation:
Consider the provided equation.
[tex]2a+b=c-4d[/tex]
We need to solve the provided equation for a.
Subtract b from both side.
[tex]2a+b-b=c-4d-b[/tex]
[tex]2a=c-4d-b[/tex]
Divide both sides by 2.
[tex]\frac{2a}{2}=\frac{c-4d-b}{2}[/tex]
[tex]a=\frac{c-4d-b}{2}[/tex]
Hence, the value of the equation is [tex]a=\frac{c-4d-b}{2}[/tex].
