Answer:

i think the answer is <u> 7 - x = 8</u>

Step-by-step explanation:

Let me explain why i think that is the answer. First off, i turned the problem around so it was easier for me to solve.

I think that it stays '7 - x' because they arent like terms so you cant combine them, so i think that stays the same. Because i cant change that, i added '2 + 9' and i got 11. I then took the 11 and subtracted it by itself and the 19. Because i subtracted it by itself, the 11 canceled out and i got 8 from the 19 - 11. Like i said, i couldnt do anything with the ' 7 - x' i ended up with 7 - x = 8.

Answer:

x = 12

Step-by-step explanation:

First you need to use the distributive property.

19 = 9 + 2x - 14

Then you should simplify (9-14)

19 = 2x - 5

+5 +5 (Then add 5 to both sides)

24 = 2x

/2 /2 (Divide by 2 to get x by itself)

12 = x

Hope this helps!!!

Answer:

x= - $\frac{1}{32}$

Step-by-step explanation:

First move the x on the right side the the left side. Now your equation is

2x+ $\frac{1}{2}$ = $\frac{3}{8}$ Next move 1/2 to the right side. Now your equation is 4x= $\frac{-1}{8}$ . Next divide both sides by 4 to isolate "x." Now your equation is x= - $\frac{1}{32}$
