2. x=9
Step-by-step explanation:
1.
2.
<u>Written Explanation: </u>
1.
-2x(3x+9)=-54
-6x-`8=54 (Distributive property)
Add 18 to both sides
-6x=-36
Divide both sides by -6 (negative divided by a negative equals a positive)
x=6
2.
2(3x+4)-3x=35
6x+8-3x=35 (distributive property)
3x+8=35 (combine Iike terms and then subtract them 6x-3x=3x)
Subtract 8 from both sides
3x=27
Divide both sides by 3
x=9
2 | 3x - 5 | - 8 = 8
=> 2 | 3x - 5 | = 8 + 8
=> 2 | 3x - 5 | = 16
=> | 3x - 5 | = 16 / 2
=> | 3x - 5 | = 8
=> 3x - 5 = 8 or 3x - 5 = - 8
=> 3x = 13 or 3x = - 3
=> x = 13 / 3 or x = - 1
=> x = 4 and 1/3 or x = - 1
So, the answer is the second option x = - 1 or x = 4 1/3
The graph of such solutions are just the point in the real line.
For x = 4 1/3, divide the segment from 4 to 5 in three equal parts (add two divisions between 4 and 5) and mark your point in the first division after 4.
