2(a-c)=4a solve for a

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
