Solve the equation 18x - 9 = 5+ 12x

Mathematics
1 answer:
Hitman42 [59]3 years ago
8 0

Answer:

x = 2\frac{1}{3}

Step-by-step explanation:

Try to get x alone on one side

 Add nine to both sides

18x - 9 = 5 + 12x

     + 9 + 9

Subtract 12x from both sides  

  18x = 14 + 12x    

   -12x          -12x

Now that you have x alone on one side divide both sides by 6

    6x = 14

\frac{6x}{6} = \frac{14}{6}

x = 2 \frac{2}{6} or 2 \frac{1}{3}

What is the value of x2+9x+20 when x could be -5, -3 or -6
ANTONII [103]

Answer:

Step-by-step explanation:

You should use a ^ to indicate an exponent. x^2 is the same as x².

x² + 9x + 20

Replace the x with (-5).

(-5)² + 9(-5) + 20 = 25-45+20 = 0

Then do the same with x = (-3):

(-3)² + 9(-3) + 20 = 9 - 27 + 20 = 2

You can do x = (-6)
