Answer 1

${\huge{\underline{\underline{\bf{Question:-}}}}}$

Subtract ( - 2x - y + 5z) from the sum of ( - 4- 3y) , ( 2+ 5x - 7z) and ( x + 5y+4z +2 )

$\huge\mathfrak\red{Answer:}$

$= ( - 4 - 3y) + (2 + 5x - 7z) + (x + 5y + 4z + 2) - ( - 2x - y + 5z)$

$= (6x + 2y - 3z) + (2x + y - 5z)$

$= 8x + 3y - 8z$

$\huge\mathfrak\red{Thanks}$

Answer 2

$\huge\boxed{\underline{\bf\green{A} \: \red{N} \: \orange{S} \: \purple{W} \: \blue{E} \: \pink{R}}}$

Firstly let's add (-4-3y) , (2+5x-7z) and ( x+5y+4z+2 )

→ ( - 4 - 3y ) + ( 2 + 5x - 7z ) + (x + 5y + 4z + 2)

→ 5x + x - 3y + 5y - 7z + 4z - 4 + 2 + 2

→ 6x + 2y - 3z

Now subtract ( - 2x - y + 5z ) from it

→ ( 6x + 2y - 3z ) - ( - 2x - y + 5z )

→ 6x + 2y - 3z + 2x + y - 5z

→ 8x + 3y - 8z
