Question

(9x−13y+30z)−(−25x+30y−25z)=​

Answer 1

Пошаговое объяснение:

(9х-13у+30z)-(-25x+30y-25z)=

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

34x-43y+55z

Answer 2

To simplify the expression (9x - 13y + 30z) - (-25x + 30y - 25z), you can remove the parentheses and then combine like terms:

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

Now, distribute the negative sign to each term inside the second set of parentheses:

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

Now, combine like terms by grouping the x, y, and z terms:

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

Combine the x terms, y terms, and z terms separately:

34x - 43y + 55z

So, the simplified expression is:

34x - 43y + 55z
