Answer:

x=-2

Step-by-step explanation:

Replace n(x) in the first equation to 18. After you get 18=20-x. You subtract 20 from each side to get -x=2. Since there's still a negative sign on the left side, you divide both sides by negative 1. As a result you get x=-2.

Solve the following equation-<br> p-4=(-9)+p
Mashcka [7]
Simplifying p + -4 = (-9) + p
Reorder the terms: -4 + p = (-9) + p -4 + p = -9 + p
Add '-1p' to each side of the equation. -4 + p + -1p = -9 + p + -1p
Combine like terms: p + -1p = 0 -4 + 0 = -9 + p + -1p -4 = -9 + p + -1p
Combine like terms: p + -1p = 0 -4 = -9 + 0 -4 = -9
Solving -4 = -9
