Answer 4

the sum of 2x+3y - 6z and 5x-3y
= (2x + 3y -6z) + (5x - 3y)
= 2x + 5x +3y - 3y -6z
= 7x - 6z

To get 8x-y+5z from the sum of 2x+3y - 6z and 5x-3y, we need to add something. Let that something be A
[ (2x + 3y -6z) + (5x - 3y) ] + A = 8x-y+5z
( 7x - 6z ) + A = 8x - y + 5z

Subtract both sides by 7x
( 7x - 6z ) + A - 7x = 8x - y + 5z -7x
A - 6z = x - y + 5z

Add 6z to both sides
A - 6z + 6z = x -y + 5z + 6z
A = x - y + 11z

So, to get 8x-y+5z from the sum of 2x+3y - 6z and 5x-3y, we need to add x - y + 11z.
