Simplify by combining like terms: -4\left(2x-y\right)+y+5\left(x+y\ri ght)−4(2−)++5(+) − 4 ( 2 x − y ) + y + 5 ( x + y ) ; use NO spaces when typing in your answers.

-3x+10y

Step-by-step explanation:

Given the expression , we are to simplify by combining the like terms. On simplification we have;

Open the parenthesis:

Collect the like terms:

Sum up the resulting expression

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

47 - 90 = 43

43 - 180 = x

x = 137
