Answer:

[tex]7.3(x+3.1)-2.71(3x-4.9) = - 0.8x+ 35.909[/tex]

Step-by-step explanation:

We want to simplify:

[tex]7.3(x+3.1)-2.71(3x-4.9)[/tex]

We use the distributive property to expand the parenthesis to obtain:

[tex]7.3(x+3.1)-2.71(3x-4.9) = 7.3x + 22.63 - 8.13x + 13.279[/tex]

We group like terms on the right:

[tex]7.3(x+3.1)-2.71(3x-4.9) = 7.3x - 8.13x + 22.63 + 13.279[/tex]

This finally gives us:

[tex]7.3(x+3.1)-2.71(3x-4.9) = - 0.8x+ 35.909[/tex]
