Given:
subtract the sum of 5x - 4y +62 and - 8x - y + 32 and- 3x + 5y - 82
Solution:
(5x - 4y + 6z )+(-8x + y - 2z)
(5x - 4y + 6z )+(-8x + y - 2z)= 5x - 4y + 6z -8x + y - 22(5-8)x +(-4+1)y + (6-2)z
(5x - 4y + 6z )+(-8x + y - 2z)= 5x - 4y + 6z -8x + y - 22(5-8)x +(-4+1)y + (6-2)z= -3x - 3y + 4z
Adding 12x - y + 3z and -3x + 5y - 8z:(12x - y + 3z )+(-3x+ 5y - 8z)
(12x - y + 3z )+(-3x+ 5y - 8z)= 12x - y + 3z -3x + 5y - 8z
(12x - y + 3z )+(-3x+ 5y - 8z)= 12x - y + 3z -3x + 5y - 8z= (12-3)x +(-1+5)y + (3-8)z
= 9x +4y -5z
(9x +4y -5z)+(3x + 3y - 4z)= 9x+4y-5z+3x + 3y -4z
: (9+3)x +(4+3)y + (-5-4)z= 12x +7y-9z
