Answer 2

I'm sorry, but the equations you provided are incomplete or contain errors. Let's go through them and try to clarify what you mean:

a) -3,2a + 4,8 = -2(1,2a + 2,4)

In this equation, you have the variable "a" and some numerical values. However, there seems to be a missing value or operation. Please provide the complete equation, including any missing values or operations, so I can help you solve it.

b) - = х

It appears that there is an incomplete equation here as well. The equation lacks an expression on the left side or a value to be equated to "x" on the right side. Please provide the complete equation, and I'll be happy to assist you further.
