Answer:
True for all x.
Step-by-step explanation:
1. Expand 1/3(6-9x)
2-3x
2. Expand -1/5(15x-10)
-3x+2
3. Subtract 2 from both sides.
2-3x-2 = -3x+2-2
4. Simplify.
-3x = -3x
5. Add 3x to both sides.
-3x + -3x = -3x + -3x
6. Simplify.
0=0
Both sides are equal, so it is true for all x.

Step-by-step explanation:
:)
If you do the proportion, you have to put 1/5 = 20/100. The 20 represents the percentage. Then you have to say to yourself that how many time 5 goes to 100, well its x20 then if we multiply 1 x 20 we'll get 20. So, he is correct, 1/5 = 20%. Remember what number we think of when we hear the word percent, the number is 100.
