Question

What value of x makes this equation true?
`12x - 15 = 6 - 3x`

Answer 1

The value of x that makes the equation true is;

`x\text{ = }(7)/(5)`

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;

`\begin{gathered} 12x-15\text{ = 6-3x} \\ 12x\text{ + 3x = 6 + 15} \\ 15x\text{ = 21} \\ x\text{ = }(21)/(15) \\ \\ \text{ x = }(7)/(5) \end{gathered}`
