Question

3/10x - 16 = 9/10x + 4 equals what?

3/10x - 16 = 9/10x + 4

Answer 1

`-0.03`

Explanation:

`3/(10x) - 16 = 9/(10x) +4`

Multiply each side by `10x`. `10x` is canceled out and `-16` and `4` are multiplied by `10x`.

`3 - 160x = 9 + 40x`

Solve for `x` by moving everything with that variable to one side.

`-6 = 200x`

`-0.03 = x`
