Simplify by combining like terms: -4\left(2x-y\right)+y+5\left(x+y\right)−4(2−)++5(+) − 4 ( 2 x − y ) + y + 5 ( x + y ) ; use NO

Answer:

-3x+10y

Step-by-step explanation:

Given the expression $-4\left(2x-y\right)+y+5\left(x+y\right)$ , we are to simplify by combining the like terms. On simplification we have;

$= -4\left(2x-y\right)+y+5\left(x+y\right)$

Open the parenthesis:

$= -4(2x)-4(-y)+y+5(x)+5(y)\\\\= -8x+4y+y+5x+5y$

Collect the like terms:

$= -8x+5x+4y+y+5y$

Sum up the resulting expression

$= -8x+5x+4y+y+5y\\= -3x+10y$

Hence the required expression on simplification is -3x+10y
