what is a slope

3x-5=3x+5 There is no solution.

3x+5=20 x=5 since 5x3+5=20

3X + 6 = 21 subtract 6 from each side 3X = 15 divide both sides integers by 3 X = 5 =======check 3(5) + 6 = 21 15 + 6 = 21 21 = 21 ========checks

4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3

4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3

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

-3x + 10x - 5 + 26 = 7x + 21

if 3x+5=x+19 then x=7

If: 3x+5 = 4x+1 Then: x = 4

6x+5=3x+5 5=9x+5 x=0

3x + 5 = 6x + 23 -3x = 18 x = -6
