Step-by-step explanation:
The expression
4.7x + 10.4 + 15.3x − 8.4x + 15.6
can be simplified in a few stages. First of all, we use the commutative property of addition to swap terms 2 and 3.
4.7x +15.3x +10.4 -8.4x +15.6
Next, we use the distributive property to factor x from the first two terms.
(4.7 +15.3)x +10.4 -8.4x +15.6
Now we perform addition.
20x +10.4 -8.4x +15.6 . . . . . . . . equivalent expression
