The value of x that makes the equation true is;
[tex]x\text{ = }\frac{7}{5}[/tex]Here, we want to get the value of x that makes the equation true
All have to do here is to solve the equation for x
We have this as follows;
[tex]\begin{gathered} 12x-15\text{ = 6-3x} \\ 12x\text{ + 3x = 6 + 15} \\ 15x\text{ = 21} \\ x\text{ = }\frac{21}{15} \\ \\ \text{ x = }\frac{7}{5} \end{gathered}[/tex]
