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+5 = 2x+13 3x-2x = 13-5 x = 8

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

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

-5

x = 5

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

3x+5=20 3x=15 x=5

-3x + 5 = 20 -3x = 15 x = -5

x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0

No, the two lines are not perpendicular.

6x + 4 = 3x + 19 3x + 4 = 19 3x = 15 x = 5 Check it. 30 + 4 = 15 + 19 It checks.

3X + 5 = 203X = 15 X = 5

3X+2=2X-5 -2 -2 __________ 3X= 2X-7 -2X -2X __________ X=-7 Check: 3(-7)+2=2(-7)-5 -19=-19 :)

x+5 = 3x+15 x-3x = 15-5 -2x = 10 x = -5

3x+5=14 3x=9 x=3

x = -10

3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4

The slope equals 3
