The equations 10x = 0 and X △ 10 = 0 have no solution? Is it right or wrong? The equations 10x = 0 and X △ 10 = 0 have no solutions? Right or wrong?

The equations 10x = 0 and X △ 10 = 0 have no solution? Is it right or wrong? The equations 10x = 0 and X △ 10 = 0 have no solutions? Right or wrong?

There are solutions, all x = 0, this is correct, there is no error
Supplementary questions:
They all have solutions, so if you don't solve that sentence, you are wrong,

How to solve this equation? X + Y-Z = 0.3y-10x = 10

x+y—z=0,3y—10x=10

Let the equation of circle C1 be (x-3) 2 + (Y-2) 2 = 9, and the equation of circle C2 be x2 + y2-10x + 2Y + 10 = 0
The center distance lc1c2 | is equal to

C2: change to
（x-5)²+(y+1)²=16
That is C1 Center (3,2) C2 Center (5, - 1)
C1C2=√(5-3)²+(-1-2)²=√13
