Answer 1

1) 11x=36-x

11x+x=36

12x=36

x=36/12

x=3

2) 9х+4=48-2х

9x+2x=48-4

11x=44

x=44/11

x=4

3) 8-4х=2х-16

-2x-4x=-16-8

-6x=-24

6x=24

x=24\6

x=4

4) 0.4+3.8=2.6-0.8х

4.2=2.6-0.8x

0.8x=4.2-2.6

0.8x=1.6

x=1.6/0.8

x=2

5) 6.8-1.3=0.6х-2.7

5.5=0.6x-2.7

0.6x=5.5+2.7

0.6x=8.2

x=8.2/0.6

x=12

6)

$\frac{4}{9} x+14=\frac{1}{6} x+9\\\frac{4}{9}x-\frac{1}{6}x=9-14\\\frac{8}{18}x-\frac{3}{18}x=-5\\\frac{5}{18}x=-5\\\ x=-5/\frac{5}{18} \\\ x=-5* \frac{18}{5}\\\ x=-18$
