20x+7=5x+10 15x=3 3/15=.2 x=.2
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
(x + 7) + (x - 2) x= -7 or 2
8x-7 plus 2x equals 6 plus 5x plus 2?
3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.

If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
It is a mathematical equation, usually written like this: 5x - 7 + 2x = 3x - 2 + 4x
(x - 7)(x + 2)
