6x-2=7x+9 find x plz help

steposvetlana [31]

Answer:

$x=-11$

Step-by-step explanation:

$6x-2=7x+9$

Add 2 to both sides:

$6x-2+2=7x+9+2$

$6x=7x+11$

Subtract 7x from both sides:

$6x-7x=7x+11-7x$

$-x=11$

Divide both sides by -1:

$\frac{-x}{-1}=\frac{11}{-1}$

$x=-11$

Vikentia [17]

You can determine your speed that is Speed = (distance/Time). Mind you in this cast time should be in hour, so 30 min - 1/2 hour or 0.5 Hour

Your speed is 5/0.5 = 10 mi/hour
