To solve this equation, we need to get everything that looks like x to one side of the equation, and everything else to the other side. This means:
`3.5x-1=-1/2(-7x+2)` multiply both sides by -2
`-7x+2=-7x+2` move variables to left side, and numbers to right
`-7x+7x=2-2` simplify
`0=0`
This equation is true for all values of x, which means that its solution is all real numbers.
