Simple algebra. 1 + 3x = -x - 4 3x = -x - 5 -3x = x + 5 -4x = 5 x = -1.25
If: 3x-7+x = 5 Then: x = 3
If: 3x+7 = -14 Then: x = -7
5x-3x+x+8 = 2x+1+x+x 3x+8 = 4x+1 3x-4x = 1-8 -x = -7 x=7 Hope that helps.
3x plus 10x - 7With out knowing what ' x ' actually is.. it will reduce down to.3x + 10 x - 7=13x - 7
x = 7
3x^2

x+7
3x2 + 22x + 7 = 3x2 +21x + x + 7 = 3x(x + 7) + (x + 7) = (x + 7)(3x + 1)
If: 3x-7+x = 5 Then: x = 3
If: 3x+7 = -14 Then: x = -7
5x-3x+x+8 = 2x+1+x+x 3x+8 = 4x+1 3x-4x = 1-8 -x = -7 x=7 Hope that helps.
if 3x+5=x+19 then x=7
3x plus 10x - 7With out knowing what ' x ' actually is.. it will reduce down to.3x + 10 x - 7=13x - 7
3x+7=4x 7=4x-3x 7=x
3x + 7 = x + 13Subtract 7 from each side:3x = x + 6Subtract x from each side:2x = 6Divide each side by 2:x = 3
