Answer 1

Răspuns:

$\bf a)~ 3 - 2(x-1)=x +5 \implies 3-2x+2=x+5\implies 3x=0\implies \boxed{\bf x=0}$

$\bf b)~ 2x+10x=6(x+1)\implies 12x=6x+6\implies6x=6\implies \boxed{ \bf x=1}$

$\bf c)~ 3(2x-3)=6-5x \implies 6x-9=6-5x\implies 11x=15\implies \boxed{\bf x=\dfrac{15}{11}}$

$\bf d)~(x+1) -3x = (x-2) \implies 1-2x=x-2\implies 3x=3\implies \boxed{\bf x=1}$

$\bf e)~ 6x +10x=6(x+1)\implies 16x=6x+6\implies 10x=6\implies \boxed{\bf x=\dfrac{3}{5}}$
