Solve the equation<br> 3x-2<br> 4<br> -<br> 2x - 5- 1 + x<br> 3 6
Nataly_w [17]

Answer:

  • \boxed{\sf x=12}

Step-by-step explanation:

\sf \cfrac{3x-2}{4}-\cfrac{2x-5}{3}=\cfrac{1+x}{6}

First, let's find the LCM of 4, 3, and 6.

<u>How to find the LCM:</u>

→ List multiples of each number.

→ Find the smallest number on each list.

4: 4, 8, 12, 16, 20, 24..

3: 3, 6, 9, 12, 15, 18, 21, 24, 27....

6: 6, 12, 18, 24, 30, 36, 42...

<u>LCM: 12</u>

<u>_________</u>

Now, we'll Multiply by LCM:

\sf \cfrac{3x-2}{4}\times \:12-\cfrac{2x-5}{3}\times \:12=\cfrac{1+x}{6}\times \:12

Simplify:

\sf 3\left(3x-2\right)-4\left(2x-5\right)=2\left(x+1\right)

Now, expand, Apply the Distributive property:

\bold{ 3\left(3x-2\right)-4\left(2x-5\right)}

\sf  9x-6-8x+20

Combine like terms:

\sf x+14

________

\bold{ 2\left(x+1\right)}

\sf 2x+2

\sf x+14=2x+2

Subtract 14 from both sides:

\sf x+14-14=2x+2-14

Simplify:

\sf x=2x-12

Subtract 2x from both sides:

\sf x-2x=2x-12-2x

Simplify:

\sf -x=-12

Divide both sides by -1:

\sf \cfrac{-x}{-1}=\cfrac{-12}{-1}

\sf x=12

Travka [436]

Answer:

6 runners

Step-by-step explanation:

Each runner ran 7.5 km.  If there were n runners, then (7.5 km)n = 45 km.

Solve this for n by dividing 7.5 km into 45 km:

n = 6

There were 6 runners.
