2x - 10 =30 2x -10 = 30 +10 +10 2x = 40 /2 /2 x = 20
I am having difficulty understanding your question. 12 + 20 = 10 is obviously false (12 + 20 = 32).If 4x + 14 = 2x + 30, then x must equal 8.
30+12x = 6(5+2x)
If: 3x+20 = 2x-10 Then: x = -30
30
2x - 10 =30 2x -10 = 30 +10 +10 2x = 40 /2 /2 x = 20
10 - 3x = x - 2x + 40 10 - 3x = - x + 40 10 - 40 = 3x - x -30 = 2x -15 = x

10 + 10 + 10
Subtract 2x from each side: 30 = 10x - 50;Add 50 to each side: 80 = 10xDivide each side by 10: 8 = x
(3,3)
30+12x = 6(5+2x)
2x + 30 = 4x + 22 Subtracting 2x from both sides, 30 = 2x + 22 Subtracting 22 from both sides, 8 = 2x Dividing both sides by 2, 4 = x x = 4
If: 3x+20 = 2x-10 Then: x = -30
30
-1
2x + 6 - 6x = 30= 6 - 4x = 30= -4x = 24= 4x = -24= x = -6
