Answer :
4x - 6 = x + 9
4x - x = 9 + 6
3x = 15
[tex]x = \frac{15}{3} \\ [/tex]
x = 5 ...
Answer:
[tex]x =5[/tex]
Step-by-step explanation:
[tex]4x - 6=x+9[/tex]
Subtract x from both sides
[tex]4x -6-x=x+9-x[/tex]
[tex]3x-6=9[/tex]
Add 6 to both sides
[tex]3x-6+6=9+6[/tex]
[tex]3x=15[/tex]
Divide both sides by 3
[tex]\frac{3x}{3} = \frac{15}{3}[/tex]
[tex]x = 5[/tex]
