Best ResponseYou've already chosen the best response.0Let's solve your equation stepbystep. −8x+9x−21=−12−16 Step 1: Simplify both sides of the equation. −8x+9x−21=−12−16 Simplify: (Show steps) x−21=−28 Step 2: Add 21 to both sides. x−21+21=−28+21 x=−7 Answer: x=−7

Best ResponseYou've already chosen the best response.1now you can check ur answer substitute x for 7 \[\huge\rm 8(7)+9(7)21=1216\] both sides are equal good to go!
