4n = -10
Now divide by 4 on both sides
n = -10/4
And finally, simplify
-10/4 = -5/2

Step 1: Define
[tex]\frac{n + 1}{2} = -\frac{3}{4}[/tex]
Step 2: Solve for n
- Cross-multiply: [tex]4(n + 1) = -6[/tex]
- Divide 4 on both sides: [tex]n + 1 = \frac{-3}{2}[/tex]
- Subtract 1 on both sides: [tex]n = \frac{-5}{2}[/tex]
