Answer: [tex]\frac{4}{5}(7-6x)[/tex]
Step-by-step explanation:
We have the following expression:
[tex](1.3x+2.4)-(6.1x-3.2)[/tex]
Here we have to group similar terms, but firstly we have to solve what is inside the second parenthesis according to the rules of algebraic operations (equal signs give as a result a positive sing and different sings gives as a result a negative sing):
[tex]1.3x+2.4-6.1x+3.2[/tex]
[tex]5.6-4.8x[/tex]
This expression can be written as:
[tex]\frac{28}{5}-\frac{24}{5}x[/tex]
Applying common factor [tex]\frac{4}{5}[/tex]:
[tex]\frac{4}{5}(7-6x)[/tex] This is the result
