Answer 2

5x+2=2x-4 ----------

$5x - 2x = -4 - 2 3x = -6 x = -6/3 x = -2$

2x+1=x+11 ----------

$2x - x = 11 - 1 x = 10$

4x+9=3x+5 ----------

$4x - 3x = 5 - 9 x = -4$

5x-7-2x-2=0 ---------

$5x - 2x = 7 +2 3x = 9 x = 9/3 x = 3$

-2x+7=-4x-4 ---------

$-2x + 4x = -4 + 7 2x = 3 x = 3/2 x = 1,5$
