Question

What is the value of x. 3-2x=-1.5x.

Answer 1

`\begin{gathered} 3-2x=-1.5x \\ \text{collect like terms} \\ 3=-1.5x+2x \\ 3=0.5x \\ x=(3)/(0.5) \\ x=6 \end{gathered}`

Answer 2

`3-2x=-1.5x`

Simplify both sides:

`3+-2x=-1.5x`

`-2x+3=-1.5x`

Add 1.5x to both sides:

`-2x+3+1.5x=-1.5x+1.5x`

`-0.5x+3=0`

Subtract 3 from both sides:

`-0.5x+3-3=0-3`

`-0.5x=-3`

Divide both sides by -0.5:

`(-0.5x)/(-0.5) =(-3)/(-0.5)`

`\fbox{x=6}`

Hope this helps!
