。☆✼★ ━━━━━━━━━━━  ☾  ━━━━━━━━━━━ ★✼☆。

4(5x + 3) - 2x + 7 = 10 - 9x + 2

Expand the brackets:

20x + 12 - 2x + 7 = 10 - 9x + 2

Simplify by collecting like terms:

18x + 19 = -9x + 12

Add 9x to both sides:

27x + 19 = 12

Subtract 19 from both sides:

27x = -7

Divide both sides by 27:

x = -7/27

2. 18x+19=12-9x

3. 18x-9x=9x

4. 9x-9x=0x, which actually cancels out.

5. 9x+19=12

6. 19-19=cancels out

7. 12-19=-7

8. 9x=7

9. 9x/9=x

Calculate the circumference of the two semi circles, which equals a full circle. Then add the two sides of the track.
 Circumference is pi x diameter = 3.14 x 22.8 = 71.592, so, you would need to add 71.592 + 49.2 + 49.2  = 169.992 meters, and that would be the length of one lap of the track.
