For the first one you would insert the parantheses next to 2x6. For the second one you would do it in 3x2 and you did the third one right.

9. ¹/₃(x + 6) = 8
 ¹/₃(x) + ¹/₃(6) = 8
 ¹/₃x + 2 = 8
 - 2 - 2
 3 · ¹/₃x = 6 · 3
 x = 18

15. ¹/₅(x + 10) = 6
 ¹/₅(x) + ¹/₅(10) = 6
 ¹/₅x + 2 = 6
 - 2 - 2
 5 · ¹/₅x = 4 · 5
 x = 20

20. ¹/₈(24x + 32) = 10
 ¹/₈(24x) + ¹/₈(32) = 10
 3x + 4 = 10
 - 4 - 4
 3x = 6
 3 3
 x = 2

32. 5 - ¹/₂(x - 6) = 4
 5 - ¹/₂(x) - ¹/₂(-6) = 4
 5 - ¹/₂x + 3 = 4
 5 + 3 - ¹/₂x = 4
 8 - ¹/₂x = 4
 - 8 - 8
 -2 · (-¹/₂x) = -4 · (-2)
 x = 8

33. ²/₃(3x - 6) = 3
 ²/₃(3x) - ²/₃(6) = 3
 2x - 4 = 3
 + 4 + 4
 2x = 7
 2 2
 x = 3¹/₂

Can anyone do this please

Answer:

I know for the fact that it's the first one but I don't know the other answer

Step-by-step explanation:

An equation of a graph is y=mx+b and the B is the y-intercept which is -2 since the line is on top of -2. mx is the rise/run of -2 which is -3/2

Hope this helps, but I don't which other equation represents the graph.
