Answer:
Here you go :)
So, you can't really answer this, but you can simplify it.
Simplifying
2(a + -1c) = 4a
(a * 2 + -1c * 2) = 4a
(2a + -2c) = 4a
Solving
2a + -2c = 4a
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-4a' to each side of the equation.
2a + -4a + -2c = 4a + -4a
Combine like terms: 2a + -4a = -2a
-2a + -2c = 4a + -4a
Combine like terms: 4a + -4a = 0
-2a + -2c = 0
Add '2c' to each side of the equation.
-2a + -2c + 2c = 0 + 2c
Combine like terms: -2c + 2c = 0
-2a + 0 = 0 + 2c
-2a = 0 + 2c
Remove the zero:
-2a = 2c
Divide each side by '-2'.
a = -1c
Simplifying
a = -1c
