Alright, so 2x+2=0 (with x being the number) is what I'm getting from this. Subtract 2 from both sides to get 2x=-2, and then divide by 2 to get x=-1

How to solve step by step

Oliga [24]

Create an equation. Since all of the angles of any triangle add up to 180 degrees, our equation will be:
7x+25+9x+25+5x+25=180.
Now, jus solve for x.
Combine like terms
21x+75=180
Subtract 75 on both sides to further simplify.
21x=105
Finally, divide both sides by 21 to isolate x.
X=5
Hope this helps!
