Mathematics
1 answer:
Neko [114]3 years ago
6 0

Answer: -15a - 27

Step-by-step explanation:

McKenna made her first mistake in Step 2. You would need to multiply -5 by 3a and 6, not add it to 3 first.

The correct steps would be:  

3−5(3a+6)

3+(−5)(3a+6) Step 1

3 - 15a - 30 Step 2

-15a - 27 Step 3

2 - 3 (2x - 5) = 6x + 1
Nataliya [291]
2 - 3 (2x - 5) = 6x + 1
2 -6x +15 = 6x +1  distribute the -3 to (2x -5)
-6x + 17 = 6x + 1  add 2 + 15
16 = 12x add the -6x to the positive 6x and subtract the 1 from 17
1 1/3 = x divide 16/12
