Answer:
x = 2.5
Step-by-step explanation:
- Expand the brackets
- [tex]27+9x=12+3x[/tex]
- Subtract 3x from both sides
- [tex]27+6x=12[/tex]
- Subtract 27 from both sides
- [tex]6x=-15[/tex]
- Divide both sides by 6
- [tex]x=2.5[/tex]
Answer:
x = -3
Step-by-step explanation:
9(3+x) = 4(3+x)
9(3+x) - 4(3+x) = 0
(9-4)(3+x) = 0
5(3+x) = 0
15+5x = 0
-15 = 5x
x = -3
