3x + x + 10 + x = 5x + 10
5x-3x+x+8 = 2x+1+x+x 3x+8 = 4x+1 3x-4x = 1-8 -x = -7 x=7 Hope that helps.
3x+5<x+11 3x<6 x<2
-x + 3x = 2x
x3+3x2+3x+2 divided by x+2 equals x2+x+1
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
3x+12=x+48: 3x-x=-12+48 2x=36 x=18
3x
if 3x+5=x+19 then x=7
you mean: x+3x+3=x+18 so x=5
3x - 5x + x = -x
x+5 = 3x+15 x-3x = 15-5 -2x = 10 x = -5
