Which value of x makes the equation 4x+9=x+6 true?

Sagot :

Answer:

x=-1

Explanation:

Given the equation:

[tex]4x+9=x+6​[/tex]

First, we subtract 9 from both sides.

[tex]\begin{gathered} 4x+9-9=x+6-9​ \\ 4x=x-3 \end{gathered}[/tex]

Next, we subtract x from both sides.

[tex]\begin{gathered} 4x-x=x-x-3 \\ 3x=-3 \end{gathered}[/tex]

Finally, we divide both sides by the number beside x which is 3.

[tex]\begin{gathered} \frac{3x}{3}=\frac{-3}{3} \\ x=-1 \end{gathered}[/tex]

The value of x that makes the equation true is -1.
