Answer:
x=-1
Step-by-step explanation:
hello :
3x+9-7x=2(x+6)
3x+9-7x=2x+12
3x-2x-7x=12-9
-6x = 6
x=6/-6 = -1
Answer:
x = - [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Given
3x + 9 - 7x = 2(x + 6), that is
- 4x + 9 = 2x + 12 ( subtract 2x from both sides )
- 6x + 9 = 12 ( subtract 9 from both sides )
- 6x = 3 ( divide both sides by - 6 )
x = [tex]\frac{3}{-6}[/tex] = - [tex]\frac{1}{2}[/tex]
