Answer 1

$\huge\text{Hey there!}$

$\large\textsf{4x - 5.2y + 6y + 7.9x - 8x}$

$\huge\text{COMBINE your LIKE TERMS}$

$\large\textsf{(4x + 7.9x - 8x) + (-5.2y + 6y)}$

$\large\textsf{4x + 7.9x - 8x =}$

$\large\textsf{4x + 7.9x = 11.9x}$

$\large\textsf{11.9x - 8x = 3.9x}$

$\large\textsf{4x + 7.9x - 8x = 3.9x}$

$\large\textsf{(3.9x) + (-5.2y + 6y)}$

$\large\textsf{-5.2y + 6y = 0.8y}$

$\boxed{\boxed{\large\textsf{Answer: \huge \bf3.9x + 0.8y }}}\huge\checkmark$

Answer 2

Answer:

3.9x+0.8y

Step-by-step explanation:

4x−5.2y+6y+7.9x−8x

Combine −5.2y and 6y to get 0.8y.

4x+0.8y+7.9x−8x

Combine 4x and 7.9x to get 11.9x.

11.9x+0.8y−8x

Combine 11.9x and −8x to get 3.9x.

3.9x+0.8y

It can also be converted to fraction form:

$\frac{4y}{5}+\frac{39x}{10} = 3.9x+0.8y$
