You're still a bellend as you tried, and failed miserably, to use incorrect logic to squirm your way out of it.

Math ffs.

Explain why 3x-10=x+30?

3x - 10 = x +30
3x - x = 30 + 10
2x = 40
x = 20

That makes the original equation:
(3 x 20) -10 = 20 + 30
60 -10 = 50
50 = 50

3x - 10 = x +30
3x - x = 30 + 10
2x = 40
x = 20

That makes the original equation:
(3 x 20) -10 = 20 + 30
60 -10 = 50
50 = 50

I don't think it really mattered. The whole point of the original OP was so the word 'math' could be used to remind everyone that the bloke lives in North America now.

3x - 10 = x +30
3x - x = 30 + 10
2x = 40
x = 20

That makes the original equation:
(3 x 20) -10 = 20 + 30
60 -10 = 50
50 = 50

So, my answer of "Because x=20" was correct i presume. Seeing as the question was "Explain why". What do i win.

Simplifying
3x + -10 = x + 30

Reorder the terms:
-10 + 3x = x + 30

Reorder the terms:
-10 + 3x = 30 + x

Solving
-10 + 3x = 30 + x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1x' to each side of the equation.
-10 + 3x + -1x = 30 + x + -1x

Combine like terms: 3x + -1x = 2x
-10 + 2x = 30 + x + -1x

Combine like terms: x + -1x = 0
-10 + 2x = 30 + 0
-10 + 2x = 30

Add '10' to each side of the equation.
-10 + 10 + 2x = 30 + 10

Combine like terms: -10 + 10 = 0
0 + 2x = 30 + 10
2x = 30 + 10

Combine like terms: 30 + 10 = 40
2x = 40

Divide each side by '2'.
x = 20

Simplifying
x = 20
