3x+5 = 2x+13 3x-2x = 13-5 x = 8
If: 3x+5 = 4x+1 Then: x = 4
3x+5=14 3x=9 x=3
5=3x+2 3x+2-2=5-2 3x=3 ------ 3 x=1
(5, 1)
x + 2x + 5 = x +19 3x + 5 = x +19 3x - x = 19 - 5 2x = 14 x = 7
x = 7
3x+5=-19 subtract 5 from both sides (3x+5)-5=-19-5 simplify 3x=-24 divide 3 on both sides 3x/3=-24/3 simplify x=-8
3x-5=3x+5 There is no solution.
what is a slope
3x+5=20 x=5 since 5x3+5=20
4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
3X+2=2X-5 -2 -2 __________ 3X= 2X-7 -2X -2X __________ X=-7 Check: 3(-7)+2=2(-7)-5 -19=-19 :)
3x+5 = 2x+13 3x-2x = 13-5 x = 8
x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
If: 3x+5 = 4x+1 Then: x = 4
6x+5=3x+5 5=9x+5 x=0
