Answer:

x = 21

Step-by-step explanation:

The 2 angles form a straight angle and are supplementary, thus

7x + 9 + 2x - 18 = 180, that is

9x - 9 = 180 ( add 9 to both sides )

9x = 189 ( divide both sides by 9 )

x = 21

HELP!!!!:(<br>2.) WHAT'S THE RESULT?​
Juli2301 [7.4K]

-1+5x

You combine like terms:

Here there are two different ones.

the number without the variable (the 1s) and the one with the variable (5x)

All you have to do is combine them:

1+(-1)+(-1) = 1-1-1 = -1

5x = 5x

So, the answer would be -1+5x

Hope this helps :D
