Question

8. What must be subtracted from 7x - 3y + z - 2a to obtain 3x - 5y + 2 + 2a ?​

Answer 1

Step-by-step explanation:

let f be the unknown function

p = 7x-3y+z-2a

g = 3x-5y+2z+2a

p - f = g » p-g = f

f = 7x-3y +z -2a - (3x-5y +2z+2a)

f = (7x-3x)-(3y-5y) +(z-2z)+(-2a-2a)

f = 4x-2y-z-4a

or if

g = 3x-5y+2+2a

p-g= f

f =(7x-5x) -(3y-5y) -( 2a+2a) +z-2

f= 4x-2y+z-4a-2
