Answer:
[tex]x=-3.87[/tex]
Step-by-step explanation:
We want to solve for [tex]x[/tex] in [tex]3(2.6x-3)=4(-7-2.8)[/tex]
We expand to get:[tex]7.8x-9=-28-11.2[/tex]
We group similar terms to get:
[tex]7.8x=9-28-11.2[/tex]
This simplifies to [tex]7.8x=-30.2[/tex]
Divide both sides by 7.8 to get
[tex]x=\frac{-30.2}{7.8}= -3.8718[/tex]
