5n-2=n+18
Move n to the other side
Sign changes from +n to -n
5n-n-2= n-n+18
5n-n-2= 18
4n-2= 18
Move -2 to the other side
Sign changes from -2 to +2
4n-2+2= 18+2
4n= 18+2
4n= 20
Divide by 4 for both sides
4n/4= 20/4
Answer: n=5

Answer:
x ≥ 4
General Formulas and Concepts:
<u>Pre-Algebra</u>
Step-by-step explanation:
<u>Step 1: Define inequality</u>
-4(8 - 3x) ≥ 6x - 8
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -4: -32 + 12x ≥ 6x - 8
- Subtract 6x on both sides: -32 + 6x ≥ -8
- Add 32 on both sides: 6x ≥ 24
- Divide 6 on both sides: x ≥ 4
Here we see that <em>x</em> can be any value greater than or equal to 4.
