Answer:


\boxed {a = -c}

Explanation:

Solve for the value of
a:


2a - 2c = 4a

-Take
4a and subtract it from
2a:


2a - 2c - 4a = 4a - 4a


-2a - 2c = 0

-Add both sides by
2c:


-2a - 2c + 2c = + 2c


-2a = 2c

-Divide both sides by
-2 and dividing
-2 undoes the multiplication by
-2:


(-2a)/(-2) = (-2c)/(-2)


\boxed {a = -c}

Therefore, the value of
a is
-c.
