1. Problem Description

Solve the equation 8(x3)+2=7(x+6)-8(x - 3) + 2 = 7(x + 6) for xx.

2. Solution Steps

We start by distributing the constants across the parentheses:
8(x3)+2=7(x+6)-8(x - 3) + 2 = 7(x + 6)
8x+24+2=7x+42-8x + 24 + 2 = 7x + 42
8x+26=7x+42-8x + 26 = 7x + 42
Now, we want to isolate xx. Add 8x8x to both sides of the equation:
8x+26+8x=7x+42+8x-8x + 26 + 8x = 7x + 42 + 8x
26=15x+4226 = 15x + 42
Subtract 42 from both sides:
2642=15x+424226 - 42 = 15x + 42 - 42
16=15x-16 = 15x
Now, divide by 15 to solve for xx:
1615=15x15\frac{-16}{15} = \frac{15x}{15}
x=1615x = -\frac{16}{15}

3. Final Answer

x=1615x = -\frac{16}{15}
