Answer 1

a. 2(x-1)=3(x+1), 2x-2=3x+3, x=-5

b. | x+3 |=0, x+3=0, x=-3

c. 3x-6=x+4, 2x=10, x=5

Answer 2

$\it c)\ \ 3x-6=x+4 \Rightarrow 3x-x=4+6 \Rightarrow 2x=10 \Rightarrow x=5\\ \\ a) \ 2(x-1) =3(x+1) \Rightarrow 2x-2=3x+3 \Rightarrow -2-3=3x-2x \Rightarrow \\ \\ \Rightarrow -5=x \Rightarrow x=-5\\ \\ b)\ \ |x+3| =0 \Rightarrow x+3=0 \Rightarrow x=-3$
