Answer 1

Answer:

$- x + y - (7x + y)$

$- x + y - 7x - y$

$- 8x$

Answer 2

Subtracting 7x + y from - x + y gives - 8x

Given :

The expressions 7x + y and - x + y

To find :

Subtract 7x + y from - x + y

Solution :

Step 1 of 2 :

Write down the given expressions

The given expressions are 7x + y and - x + y

Step 2 of 2 :

Subtract 7x + y from - x + y

Subtracting 7x + y from - x + y we get

$\sf ( - x + y) - (7x + y)$

$\sf = - x + y - 7x - y$

$\sf = - x - 7x+ y - y$

$\sf = - 8x + 0$

$\sf = - 8x$

Subtracting 7x + y from - x + y gives - 8x
