3x+4/5=7-2x Please tell me man

F(x)= 4x g(x) =x-1 what is f(x) divided by g(x)

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

9/10 divide by -3/15 as a mixed number
