Answer:
x = -3
Step-by-step explanation:
<em>I hope you mean "no solution" as in 'equal to zero' because that's what I'm doing and what makes sense.</em>
<em>Start by setting the equation equal to zero.</em>
3x + 9 = 0
<em>Subtract the </em><em>9</em><em> from both sides to move it to the right side.</em>
3x = -9
<em>Divide the </em><em>3</em><em> from both sides to isolate the </em><em>x.</em>
x = -3
<em>We can check that </em><em>x = -3</em><em> is the correct answer by plugging it in and seeing if it equals </em><em>zero</em><em>.</em>
3(-3) + 9
-9 + 9
0
5-2(x+2)=12. 3(x+2)=12. 3x+6=12.
-6. -6
3x=6. Divide 6 by 3x. x=2
Im pretty sure that you could, but i would have to see the triangles.
let x be y and y be the x, so we have
