Question

Add the following by column and horizontal method:
2x - 3y,4y - z and 2z + x​

Answer 1

Answer:

=(x-3y-4z)+(2x+y-z)+(-2x+3y-2)-(2x-4y+3z)

=(x+2x+3y+y-4z-2)+(-2x+3y-2)-(2z-4y+3z)

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

=(x+7x-6z)-(2x-4y+3z)

=x-2x+7y+4y-6z-3z

=x+11y-9z

Ans: -(-X+11y-9z)

Answer 2

→ 2x + x - 3y + 4y - z + 2z

→ 3x - y - z

Column method----

2x - 3y

0 - 4y - z

+ x + 0 + 2z

__________
