5x + 9 = 4
Subtract 9 from each side:
5x = -5
Divide each side by 5:
x = -1
you cant
3x + 2x = 5x. 5x= (-4) X = (-4)/5 x= -0.8
172=x
5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
3x-4=5x+6 gives: 2x=-10 which gives x=-5
3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
3x+5=4-2x+6 5x=4-1 5x=3 x=3/5
5x+2 = 3x-6 5x-3x = -6-2 2x = -8 x = -4
If: 5x+1 = 21 Then: 5x = 21-1 => 5x = 20 Divide both sides by 5 and so x = 4
5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
The answer to the math problem of 5x plus 12 equals 93-4 is 77/5.
3x + 4 = 5x - 6 -3x -3x 4 = 2x - 6 +6 +6 10 = 2x 5 = x
