Question

2a-2c=4a solve for a

Answer 1

`\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`.

Answer 2

a = - c

Explanation:

2a - 2c = 4a

- 4a - 4a

- 2a - 2c = 0

+ 2c + 2c

- 2a = 2c

/-2 /-2

a = - c
