2x+1/6y+2x

2x+1/6y+-2x=12+-2x

1/6y+-2x+13

Dive both sides by 1/6:
1/6y/1/6= -2x+13/1/6
y=-12x+78

13 = 1/6y + 2x

multiply everything by 6 to get rid of the fraction... fractions are bad
78= y + 12x

now you can solve for y by subtracting 12x from both sides
78 - 12x = y

Sean is driving to visit his friend in another state. In the first hour, he travels 1/5 of the total distance. Second hour he tr

Answer:

The friends live 285 miles apart.

Step-by-step explanation:

Let total distance in miles Sean needs to cover to visit his friend be = $x$

On first hour distance traveled in miles is = $\frac{1}{5}\ of\ the\ total\ distance = \frac{1}{5}.(x)=\frac{1}{5}x$

Distance left to cover after first hour = $x-\frac{1}{5}x$

On second hour distance traveled = 34 miles

Distance to still left to be covered = 194 miles

Total distance to be covered after first hour will be = $34\ miles+194\ miles$ = 228 miles

Thus, the equation can be given as:

⇒ $x-\frac{1}{5}x=228$

Multiplying each term with 5 to remove fractions.

⇒ $5x-5.\frac{1}{5}x=5\times228$

⇒ $5x-x=5\times228$

⇒ $4x=1140$

Dividing both sides by 4.

⇒ $\frac{4x}{4}=\frac{1140}{4}$

∴ $x=285$

Thus, the friends live 285 miles apart.
