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]
