1. Problem Description

The problem asks to solve two equations.
Equation 1: 5(n+2)15=4(2n5)5(n+2)-15 = 4-(2n-5)
Equation 2: 2x+5=6x32x+5=6x-3

2. Solution Steps

Equation 1: 5(n+2)15=4(2n5)5(n+2)-15 = 4-(2n-5)
First, distribute the constants into the parentheses.
5n+1015=42n+55n + 10 - 15 = 4 - 2n + 5
Simplify both sides.
5n5=92n5n - 5 = 9 - 2n
Add 2n2n to both sides.
5n+2n5=92n+2n5n + 2n - 5 = 9 - 2n + 2n
7n5=97n - 5 = 9
Add 5 to both sides.
7n5+5=9+57n - 5 + 5 = 9 + 5
7n=147n = 14
Divide both sides by

7. $\frac{7n}{7} = \frac{14}{7}$

n=2n = 2
Equation 2: 2x+5=6x32x+5=6x-3
Subtract 2x2x from both sides.
2x2x+5=6x2x32x - 2x + 5 = 6x - 2x - 3
5=4x35 = 4x - 3
Add 3 to both sides.
5+3=4x3+35 + 3 = 4x - 3 + 3
8=4x8 = 4x
Divide both sides by

4. $\frac{8}{4} = \frac{4x}{4}$

2=x2 = x
x=2x = 2

3. Final Answer

The solution to the first equation is n=2n=2.
The solution to the second equation is x=2x=2.
