For each equation, determine if x=2 is a solution. -2(x-4) = 4 and is it a solution why or why not?
-3.8x= -7.4 and is it a solution why or why not?
4 (x-1) -3 (x-2) = -8 is it a solution why or why not?

-2(2-4)=4

-3.8x= -7.6

4(2-1)-3(2-2)

Step-by-step explanation:

Negative two times two equals negative four,negative two times negative four equals eight,negative four plus eight equals four.

Two times negative one point six, two times negative three six, negative six plus negative one point six equals negative seven point six.

Four times two and negative one equals four, negative three times two and negative two equals zero, four plus zero equals four.
