Kamal solved an equation as shown below.
3(x-8)= x+2x+7
3x-24 - 3x+7
-24 - 7
What is the solution to Kamal's equation?
0-24
O 7
O no solution
O infinitely many solutions
Answers
Answer:
no solution
Step-by-step explanation:
3(x-8)=x+2x+7
3x-24=3x+7
there is no solution bc both sides, when simplified, that x is not defined.
you end up canceling the 3x in both sides and so,
-24 does not equal 7

[tex]x=-1.52,2.19[/tex]
Step-by-step explanation:
Hi there!
[tex]3x^2 - 2x - 10 = 0[/tex]
Use the quadratic formula:
[tex]x=\displaystyle\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex] in the form [tex]ax^2+bx+c=0[/tex]
Plug in the a, b and c values
[tex]x=\displaystyle\frac{-(-2)\pm\sqrt{(-2)^2-4(3)(-10)} }{2(3)}\\\\x=\displaystyle\frac{2\pm\sqrt{4+120} }{6}\\\\x=\displaystyle\frac{2\pm\sqrt{124} }{6}\\\\x=\displaystyle\frac{2\pm2\sqrt{31} }{6}\\\\x=\displaystyle\frac{1\pm\sqrt{31} }{3}\\\\x=-1.52,2.19[/tex]
