Answer:
x =7
Step-by-step explanation:
3x - 9 + 12 - 6x = -18
Combine like terms
-3x +3 = -18
Subtract 3 from each side
-3x +3 -3 = -18 -3
-3x = -21
Divide each side by-3
-3x /-3 = -21 /-3
x =7
Answer:
3 places to the right

4 + 8 = 12 > 10, making it a triangle
Answer:
<span>⇒x=9</span> (positive solution)
Explanation:
<span><span>x2</span>−36=5x</span>
<span>→<span>x2</span>−36−5x=0</span>
Factor the expression:
We get:
<span><span>(x−9)</span><span>(x+4)</span>=0</span>
First solution:
<span>⇒<span>(x−9)</span>=<span>0<span>x+4</span></span></span>
<span>⇒<span>(x−9)</span>=0</span>
<span>⇒x=<span>9</span></span>
