To solve these equations, we need to first isolate the variables.

у = 6

у:3 = 276

20000 - а = 18000

а - 64000 = 360000

у = 6
This equation is already solved, and у = 6.

у:3 = 276
To solve this, we can multiply both sides by 3:
у = 3 * 276
у = 828

20000 - а = 18000
Subtract 20000 from both sides:
-а = -2000
Divide by -1 to solve for а:
а = 2000

а - 64000 = 360000
Add 64000 to both sides:
а = 424000

Therefore, the solutions are:
у = 6
а = 2000
а = 424000
