Step-by-step explanation:

  • 6x-3=11
  • 6x=11+3
  • 6x=14
  • x=14/3
  • x=2.33

  • 15=x/3+2
  • 15-2=x/3
  • 13=x/3
  • x=13×3
  • x=39

  • -4(x-1)=7(x+4)
  • -4x+1=7x+28
  • -4x-7x=28-1
  • -11x=27
  • x=27/-11
  • x=2.45

  • 3(2x+1)=6x
  • 6x+1=6x
  • 6x-6x=1
  • No solution

Answer:

Step-by-step explanation:

1)

6x-3=11

6x=11+3

6x=14

x=2.33

2)

15=x/3+2

-2+15=x/3

13=x/3

x=31

3)

-4(x-1)=7(x+4)

-4x+4=7x+28

-4x-7x=-4+28

3x=24

x=8

4)

3(2x+11)=6x

6x+33=6x

33=-6x+6x

no solution
