Question

(9x−13y+30z)−(−25x+30y−25z) ​

Answer 1

Ответ:

(9x−13y+30z)−(−25x+30y−25z) = 9x−13y + 30z +25x - 30y+25z = 34 x- 43y + 55z

Answer 2

To simplify the expression (9x - 13y + 30z) - (-25x + 30y - 25z), you can distribute the negative sign inside the parentheses on the right side and then combine like terms:

(9x - 13y + 30z) - (-25x + 30y - 25z)

= 9x - 13y + 30z + 25x - 30y + 25z

Now, let's combine like terms:

(9x + 25x) + (-13y - 30y) + (30z + 25z)

= 34x - 43y + 55z

So, the simplified expression is 34x - 43y + 55z.
