Step-by-step explanation:
GivenA=3x+5y−7z,B=2x−6y+7zand
C=5x+y+2zC=5x+y+2z
\red{ Value \:of \: A + B + C }ValueofA+B+C
= 3x + 5y - 7z + 2x - 6y + 7z + 5x + y + 2z=3x+5y−7z+2x−6y+7z+5x+y+2z
= 3x + 2x + 5x + 5y - 6y + y -7z + 7z + 2z=3x+2x+5x+5y−6y+y−7z+7z+2z
= ( 3+2+5)x + ( 5-6+1)y + (-7+7+2)z=(3+2+5)x+(5−6+1)y+(−7+7+2)z
= 10x + ( -1 + 1)y + 2z=10x+(−1+1)y+2z
= 10x + 0timesy + 2z=10x+0×y+2z
= 10x + 2z=10x+2z
Therefore.,
ValueofA+B+C =10x+2z
