Answer:
The simplest form of the expression is -11y-2.1x.
Step-by-step explanation:
The given expression is
[tex](-12.7y-3.1x)+5.9y-(4.2y+x)[/tex]
We have to find the simplest form of the given expression. So, we need to combine like terms.
After combining like terms we get,
[tex](-12.7y+5.9y-4.2y)+(-3.1x+x)[/tex]
On simplifying the above expression we get
[tex](-11y)+(-2.1x)[/tex]
[tex]-11y-2.1x[/tex]
Therefore the simplest form of the expression is -11y-2.1x.
