Answer 1

1,5(х+8)=-4х+1
1,5х+12=-4х+1
1,5х+4х=1-12
5,5х=-11
х=-11:5,5
х=-2

Answer 2

спасибо

Answer 3

1,5х+12= -4х+1
1,5х+4х=1-12
5,5х= -11
х= -11:5,5
х= -2

1/6х+3/2= -1/3х
1/6х+1/3х= -3/2
1/6х+2/6х= -3/2
3/6х= -3/2
х= -3/2:3/6
х= -3/2*6/3
х= -3

3/4х+6=2х+1
3/4х-2х=1-6
3/4х-1 4/4х= -5
 -1 1/4х= -5
-5/4х= -5
х= -5:(-5/4)
х= -5*(-4/5)
х=4

Answer 4
