-3x+1=x+9

4x-11=7-2x

Answer 1

4x - 6 = 22
4x = 28
x = 7

-3x + 1 = x + 9
-4x = 8
x = -2

4x - 11 = 7 - 2x
6x = 18
x = 3

Answer 2

a) 4x-6 = 22
    4x=22+6
    4x=28
      x=28/4
      x=7
b)-3x+1=x+9
   -3x-x=9-1
    -4x=8
      x=8/-4
      x=-2

c)4x-11=7-2x
   4x+2x=7+11
   6x = 18
     x = 18/6
     x = 3
