In order to get rid of a number times x, you need to divide. Just beucase you are working with fractions, it does not change a thing. So, in order to solve, you will divide both sides by -7/10. This gives you %28%28-3%2F5%29%2F%28-7%2F10%29%29=x. In order to divide by fractions, simply multiply by the reciprocal of the second number, which means that to solve, you will actually do %28-3%2F5%29%2A%28-10%2F7%29, which is %2830%2F35%29=x. This reduces to %286%2F7%29=x.
