Answer:
x = -8
Step-by-step explanation:
4( 3x +5 ) - 3 = 9x -7
Distribute
12x +20 -3 = 9x -7
Combine like terms
12x+17 = 9x-7
Subtract 9x from each side
12x-9x +17 = 9x-9x-7
3x +17 = -7
Subtract 17 from each side
3x+17-17 = -7-17
3x = -24
Divide each side by 3
3x/3 = -24/3
x = -8
Answer:
77%
Step-by-step explanation:
Please, do not post more than 1 or 2 questions at a time. Out of courtesy I will address one of your six questions here:
<span>2x + 4 = 3(x – 2) + 1
You are to solve this for x.
1) perform the multiplication: </span><span>2x + 4 = 3x - 6 + 1
2) combine like terms: 4+6-1 = x
3) solve for x: x = 11
4) check: Is 2(11) + 4 = 3(11-2) + 1 true?
Is 22+4 = 33-6 true? NO. Try again, looking for the mistake:
</span><span>2x + 4 = 3(x – 2) + 1 => 2x + 4 = 3x - 6 + 1
4 = x - 5
9 = x
Check: Is 2(9) + 4 = 3(9-2) + 1 true? Is 18+4 = 22 true? YES.
The solution to #1 is x = 9 (answer).
Submit your other questions separately, please.

5/1 x 6 4/15
5/1 x 94/15
Answer: 94/3 or 31 1/3
The order of operations is PEMDAS. You would work on multiplying the -6 and 3.
