Question

Simplifying Algebraic Expressions
Simplify this expression using the distributive property.

     3.1(x + 1) + 4(x – 2.3)

What is the expression in its simplest form?
3.1x + 3.1 + 4x – 9.2
0.9x + 9.2
7.1x – 6.1
12.4x + 6.1

Answer 1

Distribute and combine like terms:

3.1(x + 1) + 4(x − 2.3)
= 3.1x + 3.1 + 4x − 9.2
= (3.1x + 4x) + (3.1 − 9.2)
= 7.1x − 6.1

So the simplest form is 7.1x − 6.1.
