Question

simplify (2x+4y-6z)-(3x+4y-2z)

Answer 1

( 2x + 4y-6z)-( 35 + 4y - 2z)

= 2x + 4y - 6z - 3x - 4y+ 2z
= 2x -3x+ 4y - 4y - 6z+2z
= -1x 0 - 4z
= -x - 4z

Answer 2

hi,
first of all we will open the brackets.
REMEMBERB THAT IF THE BRACKET IS PRECEEDED BY MINUS SIGN THEN THE SIGN OF THE TERMS INSIDE THE BRACKET CHANGE.

(2x+4y-6z)-(3x+4y-2z)
2x+4y-6z-3x-4y+2z
now bring the like terms together.
2x-3x+4y-4y+2z-6z
-x-4z is the answer.
