Simplify this Algebra 1 Question?

Simplify 9 + 2.5x - 13 + ( - x )

1) Distribute the - 1 in front of the parentheses (The "one" is not written because it is understood.)

9 + 2.5x - 13 - x

2) Collect like terms

2.5x - x + 9 - 13

3) Combine like terms

1.5x - 4

It's not a question it is an equation.

9 + 2.5x - 13 + (-x)

[9 - 13] + [2.5x - x] --> group like terms

-4 + 1.5x --> simplify

1.5x - 4 --> the more traditional way to write it...

Note: this is NOT an equation and you can get marked down on a test if your teacher is anal about it. No equal sign = no equation. This is an "expression." Expressions have no "solutions," but they can be simplified or reduced.

Just combine like terms

9+(-13) = -4

2.5x+(-1x) = 1.5x

The simplest form of the expression, then is 1.5x-4

Simplify is just one of those issues that is crucial, that entails expert help regarding
