## Thinking Mathematically (6th Edition)

5 + 3(x - 4) = 8(x - 4) = 8x - 32 Simplifying the Left-hand side: 5 + 3(x - 4) =5 + 3x-12 =3x-7 Right-Hand Side = 8x - 32 Left-hand side$\ne$Right-Hand Side Thus the statement is false. In order to make the statement true, add (x-4) beside 5. This will make 5 be multiplied by (x-4). (x-4) are now common factors and can then be grouped together to form 8(x - 4) New statement: 5(x - 4) + 3(x - 4) = 8(x - 4) = 8x - 32
