Step 1: Simplify both sides of the equation. 7−3x=3(3−x)−2 7+−3x=(3)(3)+(3)(−x)+−2(Distribute) 7+−3x=9+−3x+−2 −3x+7=(−3x)+(9+−2)(Combine Like Terms) −3x+7=−3x+7 −3x+7=−3x+7 Step 2: Add 3x to both sides. −3x+7+3x=−3x+7+3x 7=7 Step 3: Subtract 7 from both sides. 7−7=7−7 0=0 So all real numbers
First 7−3x=3(3−x)−2 7+−3x=(3)(3)+(3)(−x)+−2(Distribute) 7+−3x=9+−3x+−2 −3x+7=(−3x)+(9+−2)(Combine Like Terms) −3x+7=−3x+7 −3x+7=−3x+7 secound −3x+7+3x=−3x+7+3x 7=7 third 7−7=7−7 0=0
